And so far as I am aware, Sony didn't gave any code back.

Why should they? If the FreeBSD project wanted code to be given back, they would have used the GPL. It's Sony's right as a corporate person to take BSD-licensed code and profit from it without any sort of "giving back."

I vaguely recall hearing they did contribute some code to llvm/clang though, which FreeBSD uses.

sony has contributed patches. They are also involved in some of the BSD conferences.
