True privacy is a myth these days. Even when you don't explicitly share information, data mining techniques can profile you with greater accuracy than you might expect. Unless you want to board up your windows and pay for everything with cash, there's no way around it. Sadly, all tech companies are forced to give the government information when they are served warrants, etc. If anyone is to blame for this practice, it's the government, not the companies obeying the law.

I use Google's services, including Google Wallet, because I get a lot of utility out of them. I'm not really concerned about their algorithm's discovering some of my likes and dislikes. I will be subjected to ads whether I like it or not. At least this way, more of them are for things I might actually be interested in.
