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. Should somebody have embraced, extended, and extinguished it by now?
Why haven’t they?
