Everyone is better off with Adobe on the "same team". They were trying to swim upstream and they knew it. The web dev world was marching forward with or without them and I'm glad they made the difficult but correct decision to embrace what is clearly the future.

Despite the widespread hatred for the Flash runtime it's almost universally agreed that Adobe makes great tools to create Flash things, and now we have them making those tools for the web. Which is also widely acknowledged as a giant hole in the modern web dev process. This really is a good thing for almost everyone as far as I can see.
