You're being a bit obtuse here yourself. The original premise of Plex was to stream your own media on your own network. I was a very early user of it, before these additional "features" that were pushed more by the Plex team than by user demand were added. They made it so you had to hack the xml config file to be able to use it in the traditional no login way, that was a pretty hostile move in my opinion and was the first eyebrow raiser for me. They also made it so you had to have a paid account to use any of the mobile clients in a clear monetization move there is no technical reason why you can't open your plex server to the internet and connect a mobile app that way, that's what jellyfin allows. I worked around this for a while by connecting to my home network on a VPN and just using chrome mobile to stream but it was less than ideal, obviously. Yes then they offered the proxying service with dynamic TLS cert generation as another paid for service, I remember it, but having never had a plex account let alone a paid one it was no interest to me. Do you work for Plex? Because your post reads like you do, especially the attitude of people not knowing what features they want and needing Plex to tell (sell) them.
