Imagine you are born and raised in brasil. You have a netflix subscription there and you can watch the things you want with brasilian audio and/or subs.
Now, you move to another continent. You can watch the same content, but not with the audio/subtitles in a language you understand.
When this person torrents this content, each and every language audio and/or subtitle is simply available and thus this person can watch the content, they were willing to pay for, without problems.
Once this problem is solved, we get to the 'problem' of having content available scattered over 584778964 apps or available in one.
