How is Apple working to change the landscape?

First of all putting theora as a baseline in the spec isn't forcing
anyone to do anything. If for whatever reason you can't implement the
spec at the current time (due to hardware not existing in devices that
you care about) then simply don't implement in these devices yet. For
authors that is no different from you not having had the engineering
resources to implement a feature yet, and no different to having to
support old UAs.

Second, building momentum behind Theora will actually go a long way
towards solving the underlying issue. The main advantage H.264 has is
its popularity. The popularity is why there is hardware support, and
popularity is (if I understand you correctly) why you aren't worried
about unknown patents.

Would Apple support such an arrangement? And would an outcome of such
a search affect Apples willingness to implement Theora?
