Fair point. I am not a heavy GA user, I just use the basic functionality.

Nevertheless, I don't feel iffy about my Interests profile participating in aggregate data available to the sites I visit. Since virtually all sites are free of charge, giving some of that insight back seems like a fair trade.

That said, having ALL that data available to Google without anonymization is a bit more worrying, although I haven't seen many examples where it hurt someone in real world.
