I understand there is way too much money in advertising, and therefore data collection, to ever go away. What I want in an ideal world is transparency. If I opt-in to using web services that collect + sell my browsing data, I want to know what data is collected, how much, and who it is sold to and for what. Then I can make an informed decision about the services I'm utilizing and if I think they are handling data responsibly.
As far as I'm concerned, targeted ads are fine. If you're going to berate me with visual pollution for crap I don't need, at least let it be somewhat relevant to my life. What I don't want is "targeted information", "curation", or any other buzz word that describes showing me filtered content based on an algorithm. Of course that is already happening, but it could be much, much worse.
