BSD has nothing to feel mournful about. Its derivatives are frequently found in the data center, but largely unremarked because it’s under the black box of storage and network appliances.
And it’s in incredible numbers - hundreds of millions of units - of game consoles.
The BSD family isn’t taking a bow in public, that’s all.
Orbis OS has very little of FreeBSD, if that is what you mean.
And outside NetFlix, there aren't many big shots talking about it nowadays.
It looks exactly like a BSD syscall table. Including one I wrote an implementation of. https://www.psdevwiki.com/ps5/Syscalls
Usually an OS is a little bit more than a syscall table.
