And yet Google does release a lot of stuff. They are doing a lot to advance the state of the art in day-to-day computing. Operating systems, programming languages, lots of stuff.

I'm not even sure how anyone justifies claiming MS or Google research is _inferior_ to the other's. If we have that much insight into what is superior, then surely we've already won and know where to throw our bucks?
Regardless, Google already does plenty of work in these fields. This year, they've expanded to partnerships with NASA, USRA, and D-Wave with a new AI Lab -- https://www.youtube.com/watch?v=CMdHDHEuOUE.
