And one with much deeper implications on how they operate. It's easy for Meta to just hire more moderators or treat reports of exploitation with higher priority; if this verdict stands, I think they have no realistic choice but to abandon usage targets.

Realistically they will hire expensive lawyers, pay out hundreds of millions to billions in settlements, fire lots of people (workforce is predominantly American), etc.

Even if they do what you're saying, lots of people who've used any Meta property in the last 15 years has a potentially viable case, and no future work can swat those away
