Hardly. They earn money by being paid by their users, but they can earn more money by being paid by their users and also selling their users' data. The goal is more money, so it makes sense for them to do that. It's not crazy.

I'm sorry if I'm coming across harsh here, but I'm seeing this same error being made over and over again. It's being made frequently right now thanks to the big shakeups happening in social media and the sudden rise of AI, but I've seen it sporadically over the decades that I've been online. So it bears driving home:
If you are about to give your content to a website, check their terms of service before you do to see if you're willing to agree to their terms, and if you don't agree to their terms then don't give your content to a website. It's true that some ToS clauses may not be legally enforceable, but are you willing to fight that in court? If you didn't consider your content valuable enough to spend the time checking the ToS when you posted it, that's not WordPress's fault.
If you give someone something and they later find a way to make the thing you gave them valuable, it's too late. You gave it to them. They don't owe you a "cut." Check the terms of service.
