Signal isn’t federated [1][2][3.1]; it’s decentralized [1][2][3.2]. Though, for all practical purposes, I would generally argue that it’s centralized.

Signal relies on centralized servers that are maintained by Signal Messenger. In addition to routing Signal’s messages, the servers also facilitate the discovery of contacts who are also registered Signal users and the automatic exchange of users’ public keys. […]

One of the controversial things we did with Signal early on was to build it as an unfederated service. Nothing about any of the protocols we’ve developed requires centralization; it’s entirely possible to build a federated Signal Protocol-based messenger, but I no longer believe that it is possible to build a competitive federated messenger at all. […] [interoperable protocols] [have] taken us pretty far, but it’s undeniable that once you federate your protocol, it becomes very difficult to make changes. And right now, at the application level, things that stand still don’t fare very well in a world where the ecosystem is moving. […] Early on, I thought we’d federate Signal once its velocity had subsided. Now I realize that things will probably never slow down, and if anything the velocity of the entire landscape seems to be steadily increasing.
- ¶“Stuck in time”. “Federation and control”. ¶6.
An open source infrastructure for a centralized network now provides almost the same level of control as federated protocols, without giving up the ability to adapt. If a centralized provider with an open source infrastructure ever makes horrible changes, those that disagree have the software they need to run their own alternative instead. It may not be as beautiful as federation, but at this point it seems that it will have to do.

Yeah. I love Signal but it doesn’t belong in that list. Dansup (creator of loops and pixelfed) is apparently working on “Sup” that will be a decentralized alternative to whatsapp.
To me this person sounds like they have too many big projects at once. I wish them success tho
Yeah… I’m bit afraid of “kbin Ernest Effect” (not sure what a proper term is) where personal issues pile up and the sole head developer just disappears.
Haven’t followed dansup much but from what I understand he is much more open to pull requests and listening to the community, but time will tell. Right now I appreciate and love his effort, giving, and the impact on fediverse he is brining.
The kickstarter was a good idea.
100% agree >.> Like as much as i love (and trust) Signal i would never call it the same as Mastodon or Matrix for Example >.> This was like comparing Appels and Oranges -.-
Delta.chat already exists
Matrix?
XMPP is an established federated messaging app with encryption.
There isn’t much information about “Sup”, but if I had to guess it could be that dansup is making sup app with XMPP(rotocol) as the messaging protocol.
Originally it was supposed to be ActivityPub based, but recently they posted something about it being for XMPP, Matrix and IRC as well 🤷♂️ Maybe they decided to fork Pidgin 😂
IMHO Sup. isn’t going to happen. They will have their hands more than full with Pixelfed’s new popularity and maybe Loops.
Oh! didn’t know that, I thought activitypub can’t be used for secure messaging. Lol really hope its XMPP!
Yeah I didn’t take it that seriously when it was announced right now. Just hope pixelfed stays afloat amidst the user flood and hope he can publish loops as open source soon!
Bro put citations in his lemmy comment 💀
I wish more people did that ngl 💀
I wish Boost understood the collapsible spoilers.
On my client, it’s all expanded and I see all the formatting characters. It looks/works great in a browser though.
Don’t let perfect be the enemy of good
My comment wasn’t protesting the use of Signal; it was rather clarifying the misinformation in OP’s post — ie misinformation that Signal is a federated service.
but I no longer believe that it is possible to build a competitive federated messenger at all.
The fact that we have a telephone system that works with separate providers contradicts this sentiment. If I want to pick up the phone and talk to my cousin’s puppy in New Zealand, I can do that without creating an account on his provider’s service.
I don’t understand why we’ve forgotten this as a society. Yes, it was difficult to upgrade the phone systems over the past century, but it’s worth it in my opinion. I really wish we’d start seeing government regulation that says “you should be able to talk to someone on a service without having to create an account on said service.” I thought the DMA would do this, but sadly, Whatsapp still requires an account to talk to people using that service. Very disappointing.
it’s decentralized
No it’s not. From literally your own comment:
Signal relies on centralized servers
For a decentralized messenger use https://delta.chat/
it’s decentralized
No it’s not. From literally your own comment:
Signal relies on centralized servers
I was using “decentralized” to mean that there isn’t centralized control over ownership of the service in general — eg anyone can spin up their own server (impractical, imo, pushing it more towards being centralized) and people can use it (making it decentralized, imo (Please correct me if I am wrong, but I do think my usage of the term is appropriate in this way.)), but people who use that server can only communicate with that server (making it not federated). But yes it could still be said to be centralized in that it operates on a client-server model [1].
This is more an argument of definitions, though. I’m not trying to claim anything in bad faith.

That’s just open source, not decentralized. I can’t find a definition of decentralization that would even make it vague. From Wikipedia:
Decentralization is the process by which the activities of an organization, particularly those related to planning and decision-making, are distributed or delegated away from a central, authoritative location or group and given to smaller factions within it.
Signal has a central authoritative server and to use it with any other server you have to modify the source code.

Signal is hostile to third party clients like Molly.im as well
That’s not true. Moxie only had a problem with a fork called “LibreSignal” because it was using their name. He didn’t want users to confuse the apps.

For the avid readers out there, bookwyrm is a fantastic alternative to goodreads.
Yes it’s excellent! Also noting for those that aren’t aware: Goodreads is owned by Amazon.
Is there a way to automatically add books to it when a book in my Calibre Library gets marked as completed?
Unfortunately, the switch from YouTube to PeerTube has not worked for me so far. I can’t find a decent instance (not full of right-wing/conspiracy content) with interesting stuff that also allows me to make an account.
Yes finding the right instance on peertube is a nightmare — and also the general lack of quality content, or subtitling, which makes it as good as useless for deaf people like me.
Ah. I see…

Don’t worry, your successor isn’t offering anything big. You’ll still be around for many more days to come.
I don’t get the joke
Signal is not Fediverse! Element/Matrix is!
Element/matrix aren’t part of the fediverse, either. It doesn’t speak AP.
Matrix is federated, Signal is not.
although it is federated, it isn’t apart of the fediverse, as it doesn’t use activitypub.
I’d argue it’s part of “the fediverse” but not “The Fediverse”.
Are we claiming now that Activity Pub is the only protocol that we can use for the fediverse? I think XMPP is roughly 30 years old at this point, and I’m pretty sure Activity Pub is much younger than that. I could be wrong though.
But regardless, I don’t see why Activity Pub has to be the only protocol we accept to be considered a part of the fediverse. It’s not even like different AP implementations talk to each other all that well. My understanding is that Mastodon doesn’t federate that well with Lemmy, and I haven’t seen Loops or Pixelfed on Lemmy yet either.
I’d be happy to be corrected on any of this though, I haven’t looked too closely into exactly how AP works or how it’s supposed to interoperate with different applications.
I’d like to argue that using AP is an inconsistent rule for membership. For example, Diaspora has been considered to be part of the fediverse from early on, but it doesn’t use AP.
I don’t really know where to draw the line. AP simply isn’t suitable for some applications, but it makes sense to include it for branding
Absolutely, signal isn’t federated, but I don’t want my messaging app to be federated. I want my social media to be federated. Lemmy is good because it’s open. Signal is good because it’s shut.
Don’t use Matrix the devs knew about sidechannel vulnerabilities and ignored them for years. This is peak negligence and should immediately disqualify you from touching anything security related.
the author literally picked random projects from github tagged as matrix, without considering their prevalence or whether they are actually maintained etc.
if you actually look at % of impacted clients, it’s tiny.
meanwhile, it is very unclear that any sidechannel attack on a libolm based client is practical over the network (which is why we didn’t fix this years ago). After all, the limited primitives are commented on in the readme and https://github.com/matrix-org/olm/issues/3 since day 1.

Hear me out.
Creators should be hosting peer tubes. And they should host exclusively their own content. Fans of their can subscribe to whatever systems they want to pay and support.
For creators, it’s a backup for when YouTube the project inevitably fails. For fans as well. But it’s also a backup of their content.
Tech-savvy content creators, sure…
Your average content creator that wants to make Minecraft videos? Unrealistic.
I hate the monopoly Youtube has, but all of the federated alternatives have a learning curve the general public isn’t willing to deal with.
Not to mention it lacks any (ethical) monetization options. And the app is absolutely rudimentary, lacking even basic functionality.
Framasoft made it clear they don’t want to make it a Youtube alternative though, however it could be through plugins. So there’d have to be a company or cooperative using it as a base to build upon, which is actually realistic. Especially European ones; not because Asia wouldn’t be interested in being more independent on the US as well, but because Framasoft is from France and Europe actively works towards this goal anyway with lots of money behind it.
For Mastodon, the people you follow will also need to switch. This is even harder than getting your friends to switch.
Well I switched from the birdsite to Mastodon because a) I like to shout in the void and b) see what other people are shouting into the void. Doesn’t really ultimately matter who’s doing the shouting. People who go to social media exclusively for news and updates are a bit strange when you really think about it. You’ve got to have the shout in you.
(I’m only being half facetious here)
A lot of youtubers make a living posting videos.
They dont have a good enough reason to risk going to a much smaller audience with no ads and no membership system
They also probably arent knowledgeable enough about computers to switch
You also can’t just switch from whatsapp to signal. I have hundreds of contacts on whatsapp that message me constantly there, and 2 on signal.
@jonjuan That’s totally true! I tried to use WhatsApp just for work and Telegram for my friends and contacts, but only my wife and mom were talking to me there 😂. However, I think it’s important to keep talking to people about alternatives. That way, we can switch from this “proprietary web” to a free one.
Unpopular Opinion Lemmy and PeerTube logo look ugly.
Unpopular opinion: your opinion is not unpopular at all.
I think it’s just the colours for the peertube one. I like that it’s three individual play icons to signify the federation aspect, but the colours are just dull.
Can anyone send me a link to the android version of loops.video, I can’t see it on the play store
It’s available on GitHub
I’ve never downloaded anything from GitHub before. How does it work? Do I need to manually update the app when a new version comes out?
We have Obtainium for that. Install it from the universal apk on their site, then add
https://github.com/joinloops/loops-app/releasesas a source and Obtainium will handle the updates for you.Okay I’ll give that a crack, thank you
Hi, I think too many people are focusing too much on the type of software included in this chart. I don’t think the goal of the person that created the chart was to create the ultimate guide to move to the Fediverse or FOSS apps with all the options available for them. I believe it prioritizes simplicity, and it’s clearly directed towards people unaware that these alternatives exist.
Most people I know don’t even know what the Fediverse is, and I think this initiative is for them.
I know that debating which FOSS/Fedi apps are the best is a big matter of concern for people that are already aware of the problems some platform have. But focusing too much on this debate not only creates more division among supporters of FOSS/Fedi, but it is also drawing attention from the main point: Bringing more people to the Fediverse.
Facebook Marketplace - > Craigslist
Great graphic! The only things I use on this list are reddit and youtube. Trying peertube now. I’m confused about whatsapp and facebook messenger - don’t people just use the texting app that comes with their phone?
as i say peertube is currently a alt to twitch as well as youtube
Anyone know if loops has a good app out, or if there’s one in the works thats coming out soon?
FB Marketplace --> Flohmarkt is missing!
Ok, downloaded peertube (because to hell with Google and YouTube) looked around… Um, is there not too much to look at right now? Are the people I normally watch on YouTube unable to be seen on peertube? Don’t get me wrong, all about decentralized everything but if the people I like aren’t there I’m feeling a bit up a creek.
Or, more likely, am I missing something? Forgive me, please, I am rather new to this concept and how to work the federations and such.
