What's ridiculous about it? Morals are subjective.

If I copy a movie that came out 80 years ago and everyone involved with it is now dead, who am I supposedly 'stealing' from or depriving of anything? Some faceless corporation who claims ownership over someone else's work? How about cases where a movie or show isn't available to buy in your area? Who's getting deprived of anything there?

You can keep your morals to yourself where they belong.
