I believe that at least in the past the entertainment industry would try to detect someone seeding a file before going after them. The idea being that someone downloading is receiving a copy (not illegal), and the act of making the copy (illegal) was done by the seeder. I'm not sure to what degree this was an established requirement vs them trying to avoid ambiguity, but my point is that this framing by Meta isn't novel. I'm not expressing a judgment on whether it's correct or if it's good.
