Dear Users, in our Terms of Service, we tell you that we won't share your data.

Psych, it wasn't legally binding.

Correct. A promise is not legally binding unless there is some sort of payment in return. The exception is if you can prove you suffered monetary damages from relying on that promise, which is basically impossible for data sharing.

> promise is not legally binding unless there is some sort of payment in return

If I recall correctly, I gave them a worldwide, perpetual license to some data.

> if you can prove you suffered monetary damages

This is a separate question (that of calculating damages) from that of whether there was a breach per se.

I can't sell my data to willing buyers for the same price anymore, because Meta illegally shared my data which reduced its value, and that's on top of the lost revenue I could have made selling my data to Meta if I was whatsapp only user.

Oh wait, I forgot those arguments only apply when companies are getting the government to go after people sharing files

Is it not at the very least false advertising?

It came with a threat that you'd lose your account of you didn't approve. That's hardly voluntary.
