I think there certainly is a use-case for people who want a family-friendly, private media solution.
A large part of more technical privacy-friendly tools like Kodi or Jellyfin is making it easier to share private solutions with less technical people. Therefore the goal of this section isn’t solely to cover personal usage, but to cover private media solutions that are applicable to indirect users as well.
You can’t take merely the amount of guides on piracy very seriously, because they are inherently more advanced topics. There is no need for a large amount of guides on how to use Kodi normally, because the normal way to use it is quite simple.
I think that assuming that most people are pirating/torrenting content or most people are doing weird things with Kodi doesn’t actually work, because those situations are merely the most vocal/obvious use-cases on the internet, not necessarily the most common use-cases.
