I mostly agree with you and frankly it is enough to have one friend who uploads their contacts to big tech firms with yours included and maybe tags you here and there and you are already uploading data without your consent.
Although what I see recently is that facebook fails to recommend anything interesting to me. I had to keep my account, but deleted everything from the day of my registration and haven’t uploaded a single thing for years.
It annoys me as well and I rather not visit any website that refuses my visit because of my adblocker. However, ads work with your unconscious and unfortunately, they work on everyone, that’s why the best is to avoid them.
