None. That doesn't mean they don't care. As I said, most people I know are annoyed by this but take these banners and tracking as a given because they don't understand enough about technology and see them everywhere. And let's be honest here, if you were to stop visiting sites that track you, you could just stop using more or less the whole internet. It's not about stopping to use these sites, it's about stopping those sites from tracking you, which almost everyone I talk to is ok with. The only people I see that defend the amount of tracking happening on the web are commenters online (here, on reddit, etc.). That leads me to believe it's mostly corporate accounts.
