I ask this because I think of the recent switch of Ubuntu to the Rust recode of the GNU core utils, which use an MIT license. There are many Rust recodes of GPL software that re-license it as a pushover MIT or Apache licenses. I worry these relicensing efforts this will significantly harm the FOSS ecosystem. Is this reason to start worrying or is it not that bad?
IMO, if the FOSS world makes something public, with extensive liberties, then the only thing that should be asked in return is that people preserve these liberties, like the GPL successfully enforces. These pushover licenses preserve nothing.


Why are they pushover licenses? Because they don’t force people to contribute back? Because a lot of companies aren’t doing that for GPL licensed software either.
Also not really sure how this would allow a takeover, because control of the project is not related to the license.
The GPL doesn’t force to contribute. But if you make changes to it, you need to have these changes reflect the liberties you yourself received. Megacorporations use the so-called “Explore, Expand, Exterminate” model, the GPL stops this from happening.
You can just wrap the software in a binary and interact with the binary and you will likely elude the GPL terms. This is kinda grey area but it would be hard to win against it in court. (I am not a lawyer)
I mean that broadly because nobody will make proprietary Coreutils or sudo as someone already pointed out.
I’ve heard it mostly as Embrace, Extend, Extinguish
It’s not so much about forcing to contribute, but rather keeping companies from selling commercial forks/having checks against profiting from work that happens to be freely available.
You can profit from GPL software. The only restriction is if you distribute it you also need to distribute modifications under the GPL.
GPL also does nothing for software as a service since it is never distributed.
GPL even explicitly allows selling GPL software. This is effectively what redhat do. They just need to distribute the source to those that they sell it to.
The GPL doesn’t place any restrictions on selling or profiting from GPL licensed works. It only requires that anyone distributing the work provides the recipients with the same rights under the GPL, ie. the right to view, modify and redistribute the source code.
This means that a company cannot take a GPL licensed work and turn it into a proprietary product.
You should look into the origins of OS X and CellOS.
Your pathetic rhetoric actively contributes to making people richer than you even richer.
Stop selling yourself out just because it’s easy.
Funny you say that because OS X shipped (and probably still ships) plenty of copyleft licensed software such as Bash. The Linux kernel is used in Android and ChromeOS.
If you want to stop corporations from profiting off your work, putting a GPL on it isn’t gonna do it. In fact no free software license will do it, because by definition they allow anyone to use and ship your software.
You don’t understand.
It’s not a problem if corporations profit off of it. It’s a problem when they extend a program without giving the public access to those changes.
