The argument, as I understand it is that the "theft" is in quotes because it's not literally copyright infringement, but fair use of an old public-domain folk tale that ends up consuming the latter.
Today, when kids know "Aladdin" they know the copyrighted/trademarked Disney character, not the traditional folk tale- that's the "theft" that happened.
If you subscribe to any concept of the public domain this is surely in it.
Would most kids around the world even know Aladdin if it wasn't for the Disney copyrighted movie?
Doesn't this mean that anyone can make a competing Aladdin story, though? Since they don't own the source IP?
