Reading Google's latest update on media codecs in Chrome, I am immensely pleased to observe how much cover they get from Firefox having held the line. Because we don't support H.264, they can say that Chrome dropping support doesn't make things worse for Web authors. I bet the fact that users can't switch from Chrome to Firefox to get H.264 also made the decision easier for them, although they're not saying that out loud :-). Hopefully we've also just been setting a good example.
Effects like this are why Mozilla is needed and why I do what I do. Hooray!
PS: I suspect that if Google had held the line harder and never supported H.264 in Chrome they'd be in a better position now, but "I told you so" is so tiresome :-).
