"If you say you don't want relevant ads, why do they still track you?"
For the same reason that telemarketers call numbers on the do-not-call list, or spammers try and get around anti-spam measures.
"Sure, you don't want spam email/calls/ads, I get that, but my advert/product is DIFFERENT. I'm doing you a favour"
