Buying stolen goods does not mean they're yours because the seller never had any ownership to begin with. The same applies here, just because there's an extra step in the middle doesn't mean that you have any rights to the data.

Some percent of their revenue as fine per case. Only way to scare these companies at this point.

A significant portion, too, not fractions of a percent. Frankly, I want the fines to bankrupt them. That’s the point. I want their behavior to be punished appropriately. Killing the company is an appropriate response, imo: FB/Meta is a scourge on society.

Meta should never have used them. Deeply unethical behaviour

Your mistake was expecting ethical behavior from Mark Zuckerberg.
