Eventually, as it happens in all public companies, the "do no evil" people are going to be out, and the "maximize the buck" people are going to be in.
Right now it's "harmless"... But people get a lot more personal in email or google searches than they do on, say, facebook.
There's some gold to be mined in there.
I don't doubt you; this may eventually happen, but for the meantime, I'm trusting them (over my ISP, anyway), with my email and backing up/saving the stuff that warrants it.
