Linux has also overshadowed BSD. Diversity matters, but so do standards. Code interaction contracts (think APIs and syscalls) are the glue to make a program that will run on a lot of diffrent software/hardware stacks (like diffrent OSes and hardware combinations). Sadly specific implementation diffrences make the genaric contracts (like UNIX/POSIX) unable to be implemented pefectly.
Another take of this is we’re losing diversity which might have some consequences in the future.
