Piracy isn’t stealing anyway. You’re not removing the data from the original owner.
But the original creation cost time and money, which you’re not reimbursing the creator for. The moral thing to do is to pay your share of that if you make a copy, even if the copy itself doesn’t cost anything.
It’s like going to a concert without paying the entrance fee. Sure it’s not a big deal if only one person does it, but the concert couldn’t even happen if everyone acted like this, or the organizers would have to pay for it all by themselves.
If you want to morally justify piracy then start with the ridiculous earnings and monopolies of big media companies, or the fact that they will just remove your access to media you “bought”. Piracy is like stealing, but sometimes stealing is the right thing to do.
Would you call it Piracy if I lend a bluray from a friend? I didn’t pay for it and yet I’ve watched it.
