The big thing about Fair Use/Fair Dealing is it’s not automatic protection from any sort of consequence, lawsuit, or prosecution. It’s only a possible defense you can try using once you’re in court about it, and there are no guarantees it’ll work out for you.

Fair Use/Fair Dealing has never been the magic “you can’t do anything to me” protection many people seem to think it is. A judge has every ability to decide what you did wasn’t a fair use and judge against you.
