Y'all are letting "most people" carry an awful lot of water for this scummy behavior here.

In my experience, most people - even most tech people - are unaware of just how much information a bit of script on a website can snag without triggering so much as a mild warning in the browser UI. And tend toward shock and horror on those occasions where they encounter evidence of reality.

The widespread "Facebook is listening to me" belief is my favorite proxy for this ... Because, it sorta is - just... Not in the way folks think. Don't need ears if you see everything!
