GDPR doesn't scapegoat anyone, it applies to anyone interacting with the EU or operating in the EU. The reason why Google/Facebook/Amazon are being mentioned is because they are the most obvious (and prolific) violators of user privacy. If we spent all our time mentioning all of the companies which violate user privacy on a systemic basis, we would never be able to get to the argument.

> Most digital companies wouldn't exist if they weren't allowed to use the data.

GDPR does not deny you the right to use user data, it regulates usage. This is such a ridiculous strawman that it doesn't even classify as a fallacy, it's just simply a lie.

> Are you going to stop using all these services that track you some way or another?

(I have stopped using many of the services you mentioned, but you're actually touching on the reason why regulation is necessary.) It is unreasonable to tell the general public they should stop using the internet if they want to maintain their privacy and dignity. And that's why there need to be regulations to provide protections for the general public when using a technology that is so central to the modern world.
