In a free market, Google is allowed to use their customer's personal information in any way they see fit, and the magical hand of the free market will punish Google if they do something wrong. So if Google finds out by reading your Gmail that you are cheating on your partner, and they extort money from you, that is just free market capitalism at work -- nothing wrong with that. By the same token, Microsoft is allowed, by the free market, to characterize Google in any way they see fit. After all, these are big corporations. The free market dictates that they can do anything they like, and so can their customers. Everybody is free, the market is free, and in the end the world is perfect and everyone is rich and happy.
