You are getting a cut of it, in the form of the voluntary usage of a free service. That's voluntary barter, you're trading your data for usage of a service and is perfectly fine.
If your point is "I want my cut in money", then you need to find someone who's willing to give you a cut in money.
> If I deny the use of my data (opt-out, right to be forgotten), I need a way to enforce that.
But that's easy to do: don't provide your data.
Your argument seems to be more like "bartering access for data should be illegal" or "it should be illegal to offer a free, ad-funded online service without offering the same service without any ads or tracking by the price that I want, a shrubbery, a nice one, not too expensive".
It isn't wrong, but it is a different argument.
PS: Sorry for the shrubbery joke, wasn't meant to ridicule anyone but myself :)
