It's a question of control; no should mean no.

Some people don't want to be tracked or monitored by advertising companies and it should be enough to just say so without companies like Facebook always trying to sneak tracking back in via dark pattens, shadow profiles, etc, etc.

For example once you've seen a website offer you the same product for different prices based on arbitrary tracking it leaves a bad taste in your mouth.

From your answer and other people's answers I feel like everyone has been brainwashed to focus on minor things like this, and totally ignore the elephant in the room.

So Facebook and Google know your religion, politics and food preferences. So what? How can they harm you with this?

They harm you when they choose what you can say, who you can talk to and who you can do business with. But literally what's the harm of ads? Making your computer a bit slower? That's such a tiny issue it's not even worth talking about.
