This is not that question though.

The question of separation of art and artist is about if you should judge the art based on the artist. That is not required or even the criticism.

In fact, most people don’t even say that HP is bad because of jk rolling. They say, it is bad to pay for HP products because jk rolling gets money from it.

I am fairly certain that people would be fine with someone pirating HP movies and watching them. Publicly screening is a different story.
