I'd disagree (I agree with the original post). Apache 2 requires a patent grant and I've heard very few instances of this license being avoided (besides the OpenBSD folk). I really do think the fear of GPLv3 comes from the anti-Tivovization requirement -- which would essentially require that 3rd parties (e.g. me) be allowed to install modifications (e.g. modified libs/binaries) of a GPLv3 application onto the controlled iPhone.
