People object to advertising because it is annoying and distracting. If the ads disappear, they got what they paid for. It's not about avoiding their "behavior being monitized", most people don't care about that at all.
People "don't care" because they do not understand the implications or the technology, not because they genuinely have no interest in privacy. Of course its easy to dupe people without technical literacy by characterizing it as some benign "targeted advertising" as if its a service being provided for you (when clearly it's not) rather than the actual answer which is "we want to follow your every movement and pattern of behaviour as if we had someone following you in an unmarked car and then sell that data to anyone willing to cough up the cash without any of your consent".
This narrative is incredibly toxic and honestly a very antisocial viewpoint of people as if they are all just stupid sheep who deserve to be exploited.
There's zero reason why its unfair for a person to both object to advertising because of the annoyance (because it is annoying) AND for a person to not want to be digitally surveilled endlessly without their consent.
Your opinion is unpopular in this subset of folks here, but it's valid.
It isn't out-of-keeping in this kind of company for a person to start discussions about personal data privacy. In fact: We chat about this stuff here all the time.
But in reality: The number of discussions I've had about personal data privacy and monetization face-to-face with people that I did not meet through a computer network, or bring up myself is exactly 1.
It's thus my observation that most people in the world care about this issue approximately...never.
(The reason they don't care may be that they don't know enough to even begin to question whether the people behind their air fryer, genealogical DNA service, garage door opener, and food delivery system may have ulterior motives.
But guesses about root causation are, at best, both tangential and broadly inconsequential. We can guess and figure and re-figure and even prove theories until the cows come home.
And it doesn't matter.
They didn't care yesterday, they still don't care today while I write this, and they will continue to not care tomorrow.)
Some of us don't care that much about advertising, but we object to surveillance.
