I have too and I 100% agree that there is a strong non-piracy use-case for Plex. However if you browse the reddit r/Plex sub it's shocking the percent of people not only using it for piracy but also working to build their own user bases - I can't tell if they receive payment or not. I've seen many posts with people lamenting the behaviors of their end users, numerous with people asking for recommendations on request systems (where end users can request content) and even a few - I kid you not - complaining that they invited random people to use their Plex server but did not receive a response or were treated poorly when the end user (that term again) used it. All that is to say...I think many people are mis-using Plex
