Let me make a clarifying statement since people confuse (purposely or just out of ignorance) what violating copyright for AI training can refer to:
1. Training AI on freely available copyright - Ambiguous legality, not really tested in court. AI doesn't actually directly copy the material it trains on, so it's not easy to make this ruling.
2. Circumventing payment to obtain copyright material for training - Unambiguously illegal.
Meta is charged with doing the latter, but it seems the plaintiffs want to also tie in the former.
