alt Hacker NewsSweets have a cost, and constitute a straightforward loss to someone if stolen. Digital copies of a file are clearly different.
There's plenty of valid arguments against piracy, but equating it to zero-sum material theft is not one of the strong ones.
This argument has always confused me. Yes, it's true that a digital copy of a video can be duplicated endlessly in a way a physical item cannot. But... so?
It's an item available for purchase at a price. If you take it without paying that price then the seller is out money they would otherwise have received. If everyone pirated Netflix's output then they would have to shut down, just the same as a grocery store would if everyone stole their produce. The only reason that doesn't happen is because piracy is a minority activity.
