Some people might say that so many companies contributing free and open code to clang/llvm instead of GCC is real world evidence against the idea that companies only contribute to free software because the GPL makes them. Or even that permissive licenses can lead to greater corporate sharing than the GPL does. Why does Apple openly contribute to LLVM but refuse to ship GPL3 anything?
According to the web, Red Hat is the most evil company in Open Source. They are also the biggest contributor to Xorg and Wayland. Those are MIT licensed. Why don’t they just keep all their code to themselves? The license would allow it after all. Why did they license systemd as GPL? They did not have to.
The memory allocator used in my distro was written by Microsoft. I have not paid them a dime and I enjoy “the 4 freedoms” with the code they gave me because it is completely free software. Guess what license it uses?
Apple makes the source code to all their core utilities available? Nobody cares but they do.
Why do they?
They are BSD licensed (very similar to MIT). According to the crowd here, Apple would never Open Source their changes. Yet, in the real world, they do.
Every Linux distro uses CUPS for printing. Apple wrote that and gave it away as free software.
How do we explain that?
There are many companies that use BSD as a base. None of them have take the BSD utils “commercial”.
Why not?
Most of the forks have been other BSD distros. Or Chimera Linux.
How about OpenSSH?
It is MiT licensed. Shouldn’t somebody have embraced, extended, and extinguished it by now?
Why haven’t they?
