I’m telling you this as someone that works in the arts, that’s just not true.
You can pirate digital material and repackage it. I see illustrators getting their designs ripped off by large scale clothing manufacturers all the time.
Similarly, I know some acts that have heard their music on adverts and films and haven’t been paid. It seems like it is being stolen if you ask me.
There needs to be protection or the creation of art becomes a luxury for those that can afford to not make money from it.
