This is a good point. I'll take it further, Google rarely seems to participate in the platforms they create. Look at Android, is there is a single pay app by Google? How many non-stock apps have teams dedicated to them (in other words, not 20% time projects)? Why would I invest my time in a platform when the parent company won't do the same?
I'm not ruling them out, I'm just saying that they invest only the bare minimum into their own platforms. Not a single pay app?
Look at what Microsoft did when they created a gaming platform. They bought Bungie.
Then look at Google and Chrome OS. They created 1, 1 new app for it (Google Talk), the rest were all existing applications built for backwards compatibility with older browsers.
