I don't know if this count as political so if it is feel free to shut it down. That being said I've recently looked into how Disney extended the copyright laws to protect Mickey Mouse from entering the public domain to the point that it also extended other characters from entering public domain. Like for example we would've gotten Spiderman in the public domain this year had it not been for Disney. The question I have is that would it be possible to reverse the extension Disney placed on the public domain so that the character that would've entered public domain earlier can actually do so at last? If not then what's stopping them? Is it a once it's in place it stays in place type of law? If someone can answer that question that'd be great.
