But Meta specifically says they took precautions to not do that, and in every client I've seen the only thing they would have to do is make sure a single checkbox which is prominently visible on the main download modal isn't checked! I'm not objecting to the use of the word "typically", I'm objecting to the explicit suggestion that Meta might have seeded the pirated works. It's unlikely and unnecessary to suggest—there's plenty else wrong with this picture so there was no need to include this idea, it's just a distraction from the real problem.
