I think you are mistaken. Hasbro can be quite defensive of their IP and will eagerly send their lawyer squads after you if make a mistake at protecting yourself from a legal perspective.
Yes there are some horrid fan creations out there but there are also so many great pieces of art, music, videos, stories, and other things made by members of the fandom. Avoiding the former is not worth losing out on the latter.
And let us be honest here. Hasbro has made a lot of mistakes in recent years, some with MLP but plenty with their other franchises too. Remember what happened with D&D some time ago? There wouldn't be any sense of remaining community here or elsewhere if it weren't for all the fans and fan works.
