What I mean is, IE9 already does play Vorbis codec. Not natively, but IE9 will play that codec if you install it on a client and then have the webserver serve a WebM MIME, but not an OGG with the same Vorbis encoding.
So yeah, I agree, I like the campaign and if it has an effect that would be great, regardless of which wins (OGG or WebM is irrelevant to me). I just thought I'd point out that it would be a more effective campaign if you backed the stronger candidate that already has partial support.
Also, apple, with 4% ish browser userbase in Safari, is sort of a triviality. The don't really have any clout and will probably have ot follow suit with whatever format Microsoft, Google, and Mozilla dictate.
