I wonder why it has taken so long for people to realize this. After all, Google's primary business--the search and advertising platform--is as closed source and proprietary as Windows.
I think there was a lot of noise and hyper that obfuscated the real messsage. Same thing happened with "Web APIs"... there is not such thing as a "Web API"... look what Twitter/Facebook and others do when they have enough traction. Web APIs and Open Source commitments seems more like a tactic than a strategy.
