That's very good point. Same goes for all the other manufacturers- they are already MPEG-LA licensees and safe from the vast majority of patent threats. So all those implementing WebM still needs to license H.264 to be safe from patent threat, and all those implementing WebM almost all have implemented H.264. WebM is only an addition to H.264. So the question for Google is always why dropping H.264 and never why adding WebM (since it is always there).
