No one is saying Google has broken contracts or the law. What is it with you Google defenders and your constant goalpost shifting? We are saying, Google is not to be trusted with claims like "we are committed to this product" because they have been caught in that lie several times before. Why are you going on about contract law and "most people and companies"? What you're saying is irrelevant.
The point is: don't expect companies or people to act against their interests. They generally haven't, don't and won't. Google isn't unique here. The problem is so pervasive in society that humans created contracts and courts to force people/companies to do things they wouldn't otherwise do.
