You think you can, but you cant. Thats how far those companies go. They just give you the illusion (and tbf, in most cases this illusion is actualy quite convenient as it avoids truly irrelevant information from being displayed).
Marketing companies are aware of people that want to isolate themselve. And they adjust for that. There is an entire division in those companies dedicated towards misleading people on that regard. And often i cant even call that bad either, as in the end… that same tracking is often part of security systems.
If you use gmail, any information google knows about you is also used to protect your gmail. Tracking is on that a satefy tool. But for someone who doesnt like it, google just adjusts the information to be more general. It gives a feeling of not being tracked, and gives a feeling of being less influenced (and in thise case, you actualy are. its by design that you are given that option. as its to keep you attached to their company).
Even if you arent using any internet connection, a lot of those companies are still aware of your existance and know quite a lot about you. Because while you avoid being registered, the people around you dont care.
And again, if such company can track you, it can use that for safety. Google knows that much about you, it can recognise any odd login (even if the other party tried to fake it as much as possible), and by that already force 2fa. And the better they can track you, the less often 2fa is required. Its sad that this disgusting behaviour by companies is actualy beneficial on many other parts. And that gives them basicly the right to just try anything.
Tracking goes realy far, and you cannot dodge it unless you live in a country where internet barely exists at all…
