A clearly partisan decision
Arguably the right stance to take (I mean, I don't think so, but I can see the point of view), but a definitely announcement by Mozilla that they're not impartial despite having no direct strategic interest in either codec. The lunacy of "someone's planning a better codec in the future so of the ones that exist now we're supporting only the one that nobody currently uses" is hard to avoid however. I remember they used to get something like 90% of their income from Google by receiving a tiny fee each time a user uses the browser's search box — is it possible they're trying to bind themselves closer to Google now that Chrome is on the scene?
