It seems this is not a rare case, I know that my friend lost great portion of his investment in the app at the point when number of users on his app was enough to start getting braking even, Google just decided that some of his users are deliberately clicking on ads. I guess that is way when you deal with company with too much power, there is no way to appall, complain, or do anything that will save your business. So, I guess, and from few stories I read if they find out that you have type of business that is interesting for them, they can simply suffocate your business by standard mafia means, like in the movies first they send a "negotiator", then they beat you a bit, and if you do not comply they "burn" your place down. So, company that had slogan "Don't be evil!" what a joke...
