Given a choice and assuming that ads stick around, I'd prefer to pull relevant personalized advertising when I want to see it. In other words, allow advertisers to put all their personalized / targeted ads into a common ecosystem, but allow me to dip into that when I'm looking for some specific purchase. That would mean that advertisers wouldn't have tracking on almost every website and inside almost every smartphone app, gathering information, taking up screen real estate, and consuming valuable bandwidth and user attention.
