This puts too much blame on the users. Individuals do not have the power to fight international mega corporations. It also ignores that, regardless of who you think is at fault, adtech violates a ton of privacy laws, at the very least in the EU. If a company doesn't have a legal basis for collecting personal data, they are not allowed to do it. Especially if it is sensitive data like medical information, religion and sexual preferences.
I don't get why we have to defend these practices or downplay them.
