GDPR is a law, not a corporation and is a recent attempt at enforcing something, and spectacularly failed at that.
Almost all eu-foreign enterprises ignore it entirely or don't actually adhere to it, even after showing a big pop-up claiming they do.
And the multinational corporations just started to hide their tracking better. For an obvious example: chrome includes a 24 bit unique identifier per installation to track you and instead of saving your PII they just build a nrr to "predict" them. Such a success, indeed.
What’s your exact point? Are you trying to say that laws don’t work and nothing can be done so it shouldn’t be tried? I don’t understand what you are trying to say.
Please give me an example of a corporation getting serious issues from any government for actions they took on foreign soil.
