Why do you believe Flash has to lose for HTML5 to win ? Kinda reminds me of someone else that once said "Microsoft doesn't have to lose for Apple to win".
Again, Google are doing as much if not more than Apple to push HTML5 into the mainstream. The fact that they are not doing it by sacrificing Flash is besides the point. If HTML5 is truly better, it will win out. In the end, the consumers win by having the choice of using the right tool for the right job.
EDIT : Like pointed out earlier :

So both you and LagunaSol need to apologize here. Google is in fact working hard on HTML5. Much harder than Apple is.
