Whether they own a physical edition of that media I don’t know. In my opinion owning a physical medium of the media is a big part in the morality discussion of piracy. But in my juriscition I’m legally not allowed to break the encryption used for CD/DVD/Blu-ray, so I’m technically pirating even if I rip my own discs. There’s obviously no way to find out for copyright owners of their discs were ripped for a private copy, but that’s also (nearly) the case for Usenet/Torrent with proper precautions. Anyway, if you read until this point, thank you!
