i know, but i in my right mind can’t give any money to google

i don’t even need good specs or sd card, just a good camera, foss rom and good battery

If you want set it and forget, you can try immutable distros like fedora silverblue, if you use bottles for running games, you can look at bazzite. If you want to tinker, then debian/arch/fedora minimal installs and build what you want

yes, but that is a separate investment

the battery thing is real. I basically can not find a laptop with weak/low power cpu and igpu, but a huge battery. I get that we can not do more than 99whr, but for weak stuff, I can not find anything above 50 practically.

epubs are effectively self contained html files, but the scripting is not there (afaik)

to add to it, you “can” add anything arbitrary, but it is not same as downloading a executable. Due to some really weird reasons, many parties were interested in using pdfs like interactive forms, for example some government forms, where you can fill a field, and you can add scripting to execute upon input and convey back. It is somewhat like javascript for pdfs, and then the onus is on the pdf readers to be compliant enough to execute such scripts, and provide enough access to your system. Many minimal pdf viewers do not implement these features, or for example pdf viewer in firefox has the option to execute, but disabled by default.

i may be wrong here, but if i remember correctly, in ech, essentially our first communication is done with some central server (which as of now is mostly cloudflare) and then they make some connection with target server, and then a channel is established between us and target. my google-fu brought me this , which is basically this only

I am unfamiliar with QUIC, and quick search basically tells it is kinda like multilane highway for udp.

If I have to compare, (not a network engineer or a person who has studied networking, to me anything beyond the simple protocols seems magic), QUIC seems like a techt which is only used after you have made connection with target, so its implementation is google independent (they seem to be lead developers for this). Whereas in ECH, cloudflare are the primary devs, but also the holder for the public keys (someone else can also be the holder, but i dont know of any other provider currently, maybe my lack of knowledge here)

Essentially just an extension of your point that implementation is lacking

for me, currently the problem is over reliance on Cloudflare, which is yet another big tech company
