Maybe I just answered my own question.
I bet you’ve taken a shortcut to save less than 1h for example.
A saying I've heard is that if the punishment for a crime is financial, then it is only a deterrent for those who lack the means to pay. Small business gets caught doing bad stuff, a $30k fine could mean shutting down. Meta gets caught doing bad stuff, a billion dollar fine is almost a rounding error in their operational expenses.
I don't know how much automatically opting everyone in to automatic photo tagging made Meta, but I assume its "less than 100% of their revenue".
Barring the point of contention being integral to the business's revenue model or management of the company being infected with oppositional defiant disorder a lawsuit is just an opportunity for some middle manager + team to get praised for making a revenue-negative change that reduces the risk of future fines.
Work like that is a gold mind; several people will probably get promoted for it.
Similarly, if Meta violates the law, and is infrequently fined a small fraction of their revenue by a small number of governments, in general it will not be a big deal for them.
