This is actually genius from the lawyers of meta. In this way they are pushing the onus onto the question of "what is illegal in regards to torrenting copyright content".

They have the money and legal team to push it to any conclusion, but that conclusion would risk so many huge industries in the Us that too many parties would be effected. That would incentivize companies to drop this case against meta and the status quo can continue.

I'm under absolutely zero illusion this will set some precedent for one way or the other. It's too valuable to too many people involved.
