Well, is slightly modified regurgitated code a copy or not? We have yet to have it answered in the age of AI, but e.g. I could not be selling Mickey Mouse merch with a simple color filter on for long.

Agree it will be interesting to see how things play out. There's enough permissive open-source licensed code available that using that only could be an option.

As for Mickey, is the difference from Oswald enough today?
