I think the difference here lies in the fact that Meta the company was downloading it for model training. The company itself was doing something illegal. If an individual was to download copyright material, it is not the fault of the VPN provider.

Here is a terrible analogy. It is sort of like blaming an auto company for someone running over a person. However, if an auto company was purposely designing cars that ran people over, then it is on the auto company. (I did say it was a bad analogy).
