It's obvious Sony is keeping certain drivers closed source while open sourcing other things, and why Nvidia decided to go with an open source driver. It's not hard to understand why, it could be some pressure or a modified GPL2.
Not true. Yes, companies choose not to contribute, so they discourage themselves. It's not inherent to the GPL.
Probably not, but possibly yes. Which is more than the cuck license guarantees. See postmarketOS and such, which would be impossible in a BSD world.
>The vast majority of vendors that use Linux embedded never contribute a single line of code
It doesn't matter. The point is just that they can be legally compelled to if needed. That is better than nothing.
>The level of contribution has nothing to do with the GPL.
None of this would be feasible if linux wasn't a platform where the drivers work. They wouldn't have worked on the linux userspace in the first place if it didn't have driver support: it wouldn't be a viable competitor to windows and the whole PC platform would probably be locked down anyways without a decent competitor. Permissive software is parasitic in this sense that it benefits from inter-operating in a copyleft environment but cooperates with attempts to lock down the market.
LLVM was made after GCC and is designed with a different architecture. It is apples and oranges.
Apple is a great example of a company that is flooding the world with locked-down devices. Everything they do is an obstacle to general purpose computing. What do they meaningfully commit to the public domain? Swift? Webkit? It is part of a strategy to improve their lock-in and ultimately make collaboration impossible.
Linux rather famously has avoided the GPL3 and is distributed under a modified GPL2. This license allows binary blob modules. We are all very familiar with this.
As a result, the kernel that matches your description above that ships in the highest volume is Linux by a massive margin. Can you run a fully open source Linux kernel on your Android phone? Probably not. You do not have the drivers. You may not pass the security checks.
Do companies like Broadcomm “collaborate” on Linux even in the PC or Mac space? Not really.
On the other side, companies that use FreeBSD do actually contribute a lot of code. This includes Netflix most famously but even Sony gives back.
The vast majority of vendors that use Linux embedded never contribute a single line of code (like 80% or more at least - maybe 98%). Very few of them even make the kernel code they use available. I worked in video surveillance where every video recorder and camera in the entire industry is Linux based at this point. Almost none of them distribute source code.
But even the story behind the GPL or not is wrong in the real world.
You get great industry players like Valve that contribute a lot of code. And guess what, a lot of that code is licensed permissively. And a lot of other companies continue to Mesa, Wayland, Xorg, pipewire, and other parts of the stack that are permissively licensed. The level of contribution has nothing to do with the GPL.
How about other important projects? There are more big companies contributing to LLVM/Clang (permissive) than there are to GCC (GPL).
In fact, the GPL often discourages collaboration. Apple is a great example of a company that will not contribute to even the GPL projects that they rely on. But they do contribute a fair bit of Open Source code permisssively. And they are not even one of the “good guys” in Open Source.
This comment is pure ideological mythology.
