If SVR4 was the one and only other Unix, you would have a point.
But that's simply not the case.

Besides, it's the API that counts, not what's under the hood.

Legal, I'm not even sure if that.  But shareholders could very well sue.
(You bought something for hundreds of millions of dollars and you're
now *giving*it away ??!?!?)

Which make them fall in Sun's camp, not BSD or SVR4.

Quite so.  But the common subset of Unix commands and interfaces has
grown so much that you can now write useful programs on top of
Unix standards.  You could not do so with POSIX.1.
