Granted - FOSS is good. But the traffic will still be running through google for almost all of this. And that, combined with their sole invention of this... I don't like it. I'm tired of them. They are too big. The worship bothers me. They've turned a corner.
Well no, Google Wave will be open source and they already published the whole protocol and API so people can build clones of it before it's even released. Microsoft releases proprietary API ran on secret protocol no once can clone unless they get sued or do crazy reverse engineering in a country where they can't be sued. Not quite the same thing.
