That's wrong – H.264 is MPEG4 Part 11 – it's part of the MPEG4 spec.
I think we need to look at why the MPEG standards see near universal
support and use: as you say, parts of MPEG4 are highly efficient
(such as H.264 and AAC), whereas alternatives of things like Theora
aren't anywhere near efficient. Also note that patents haven't
stopped the web in the past (see: GIF).
I really believe that this is too political, as history has shown
people will use whatever formats can be created easily, and are well
supported. It could be perfectly possible that anything wanting to
implement the spec is put off by needing to support a single format
that (almost) nobody uses.
