All you can do is make your own decisions concerning your personal info and data collection. Others will do what they wish. I also think it's a bit of a mistake to assume that more people don't "really understand what is going on."

From the young(er) people I've talked to, most of them understand full well what's being done with their info. It's just not that important to them. They don't care. The convenience is worth more to them. Paradigm shifts happen all the time.

Might be good, might be bad, but I suspect it will ultimately end up somewhere in the middle like these things invariably do.

EDIT: Even being not young(er) myself, I find myself caring less and less what data mining is used for by sites I choose to engage with/utilize/do business with. When it suits me, I use the same login for multiple sites (easy for them/easy for me). When it doesn't, I create new logins. I'm not being tricked; I just don't care any more. My priorities have changed. I have a feeling there's quite a few people in that same boat.
