I have been wondering recently about what the Catholic teaching regarding online piracy is. Is it a sin to pirate an old movie or TV show that is obviously no longer on TV or in theatres, and is only available on modern streaming services, or available to buy or rent online? I understand that it is different with music, and that the content in modern media makes it a moot point, since it would be sinful to watch 99% of modern movies or TV shows anyway. But that is why I only mention old movies and shows, which are morally acceptable. If a decades old show is no longer available except through purchasing online or through online subscriptions, would it still be a sin to watch a pirated version of the show?
