That's fair, but I don't know who has the intersection of Google's clout and incentives. Google's the only powerful force that has the incentive to fight for an open web, as opposed to a collection of closed silos.
My not-so-secret hope is that the lesson Google took from the Wave debacle was to first focus on making a product that's compelling and engaging to users, get a critical mass of adoption, and then release the code. I guy can dream, can't he?
