Even if you got a response it will likely not be genuine. They'd rather save face than say they were wrong.

It's just not the same. If all you need is local access or tailscale to your instance it's fine, sure you can cancel Plex. If you're sharing with friends or family or like the easy access to it that doesn't require being part of the private network. Also I like subtitles and Plex handles this way better than Jellyfin. At least last time I played with it
