What you want to look at is the size of the hate and the material reasons for it. And that’s fairly difficult to measure if you’re not paying close attention. Plex hate has been growing dramatically over the last few years because they materially changed their service. They began collecting data some time ago and now they are selling it unless you go and opt out. So the hate is much larger and louder for that reason. For me those last changes were the straw that made it clear we’re just one small push for profit away from my sailing habits getting sold to the American copyright lobby. So I’m currently trialling Jellyfin.

In addition as some have highlighted Jellyfin is markedly different from Plex or Emby in that it’s open source and if something happens to it, forking is the way out, which already happened since Jellyfin is a fork of Emby. Migrating from one open source project to its fork is usually trivial compared to migrating from a proprietary service to another one. And there’s no reasonable chance of my data ending up in the RIAA/MPAA’s hands. So the Plex -> Jellyfin switch everyone is doing is not merely switching to another horse. It’s more like switching to completely different vehicle that you can maintain indefinitely.
