Creating a brand new libc that's not under the GPL *doesn't* go against principles. That it needs to use the linux syscalls is completely obvious, and even explicitly stated as permitted (in case anyone had any doubts).
The only question is whether in a technical legalistic sense, they erred in their implementation. Making a big fuss of that seems to me is just blowing smoke.
