I understand and like Jellyfin but as my main PMS lives in a Synology NAS I think it is still the best option for my hardware (it supports quick sync through Docker or app without issues).
Plex is amazing. I got a lifetime sub 12 years ago and have no regrets. Hoping they can line up some good revenue streams and keep the great development going! I also use Jellyfin, for my my questionable content. 😄
I understand the appeal of the large influx of revenue that a lifetime subscription offers a company; but boy does it sure seem short sighted. Surely they would be better off offering some type of discount on like a 2 or 5 year deal.
