Why don't you try to stop preemptively dismissing other people. Calling it "immoral" doesn't mean anything unless you define morality and that's a loaded gun. The point is that legally, there is a distinction between depriving others of property and infringing on a copyright.
If they're different crimes, they're treated differently, addressed differently, etc... how on Earth is it not relevant to discuss?
Crime is something defined by law. Law can get wrong, and very often does.
I live in a country where it’s forbidden to organise people to jog in the park together via social network (unless you get appropriate permission, lol). Is such a 'crime' immoral?
If you think your country’s laws are always correct, think again.
There are even cases when what has been considered a crime now is considered a bravery. For example, Lithuanian book smugglers were commiting a crime, but now they are considered to have been doing the right thing.
