Appletv+ is available on android, web, and quite a few smart tvs so you can subscribe without having any other connection with their ecosystem.

It’s more likely they pirate because apple’s library is pretty small, compared to others, so it’s easier to just torrent than pay for the couple of programmes they want to watch.

It’s also more difficult to share logins with appletv (no profiles etc), so you’ll get less of the account sharing that Netflix is now trying to crack down on.
