Giving away other people's IP
Google has been busy distorting the market in its own way — by giving away its operating system when others (Nokia/Windows, Apple, Blackberry) have to invest to develop theirs, they are handing a competitive advantage to anyone willing to buy into the Android programme. This, of course, is entirely within their rights — up to the point that they are giving away not only their own Intellectual Property, but other people's as well.
