Linux feels a bit different since the complete system is not controlled by a single vendor. You have multiple distributions with their own kernel versions, libc versions, library dependencies, etc.

Mac OS has solved this but that is obviously a single vendor. FreeBSD has decent backwards compatibility (through the -compat packages), but that is also a single vendor.

No, AFAICS that can't be it. The problem is that all those libraries (libc and others?) change all the time, and aren't backwards-compatible with earlier versions of themselves. If they were backwards-compatible, you could just make sure to have the newest one any of your applications needs, and everything would work.

-compat packages exist on fedora-like systems too, usually allowing it older versions to run. I can't say how far back, but RHEL usually has current version - 1 for -compat packages.

Yep, having a single supplier of the system layer usually ends up with better backwards compatibility for binary distribution.

That's also why I have the opinion that the world is worse off due to the fact that Linux "won" Unix wars.
