Morally big studio are money making Ferengi. They're not vulnerable shrinking violets and it's difficult to muster sympathy for them even if they are in the right in particular instances. Nor am a fan of copyright law that's gotten a bit too punitive in my view.
What's so wrong with punitive copyright? Why shouldn't I have the right to sue someone who is stealing my work? Why should people be allowed to steal copyrighted material? Why do they think it's ok?
Now, do I think copyright is to long? Maybe. But, do I think it should remain punitive? Yes.
It's not hard. If you are worried you might be sued: don't make a movie using someone else's IP.
