I disagree with your claim. Can you tell me why you think that is?

You can still sell advertisement without collecting and processing large amounts of personal data. I would claim that it's even better if your ads are based on the in-page content, than users' personal information.

At the same time, legislation such as Digital Markets Act applies to large entities (currently singled out), and further compliance is going to apply to new platforms when they become "large enough".
