From a moral PoV pirating old movies isn't a big issue, especially in cases where the original makers are already dead. At that point you're only feeding Hollywood bosses, shareholders and decendants. Same as torrenting music from dead artists. I don't care for Jimi Hendrix' greedy sister or 'Authentic Brands Group', which owns the rights to Elvis Presley's music. These people can create their own art instead of living off other people's work.
What if Jimi Hendrix wanted for his sister to benefit from his work?
If we had a sane copyright system everything older than 10 years would be in the public domain
