there are certain situations in which you might be OK with the privacy implication. I, for example, would be OK with receiving a free car ride if I had to watch an advertisement while traveling in the vehicle.
a better example would be something like being fingerprinted at the airport. Where it is not strictly necessary in order to accomplish the goal of security. In general I would say Big Government is more concerning than Big Tech. Is it unfortunate that Meta and Google track you across the internet? Sure, but it's ultimately not necessary for your participation in society, unlike say being tracked in order to get a state identification card, and thus do basic things like get a bank account.
