The viewpoints expressed by some other posters seem to be based upon a self-serving letter written by Bruce Sewall.
AFAIK, self-serving letters only rarely reflect reality. Whether Apple's beleaguered GC is correct or not has yet to be determined by any court.
And keep in mind that the following companies are not so comfortable that Sewall is not (yet again) foolishly incorrect. They thought it wiser to enter into license agreements rather than to trust the opinion of a guy who is paid to express the opinion that he did not make a blunder in the license he negotiated.
