Google's power is growing, for sure. But there's nothing that says a corporate power should be curbed. British India Company started as a tea company in India and pretty much took over India via British rule. Google might do the same, but what can we do? So far Google has played the part of a good citizen, IMO (for the size of the company it hasn't really acted as an evil empire like Microsoft), but being a publicly traded company, it could easily manipulate its power. But there's no point about bitching and moaning about their takeover of NEST or Boston Robotics. Just hope that they will put it to good use much like their other projects such as free search engine, google maps, google library project, google car, google fiber etc etc.
