Yep, Microsoft is evil. But business is also evil, things should be free and available to everyone.. Google is not evil. They already know all your email messages, search queries, credit card numbers and even all clicks that you've ever made are logged on googleplex forever and ever but nevertheless, they're not evil, seriously not.. At least I know what to expect from Microsoft.
They don't know any more about any of that than any other equal service does, including Microsoft. If they have your credit card number, it's because you gave it to them willingly.
