How about, on your favorite operating system, go to “Firefox” and “Uninstall” because these folks aren’t going to get any better going forward.

I have had a plex instance but when they started adding their own movies and crapola into it, and requiring logins and etc etc etc I started keeping a Jellyfin instance live as a hedge. I still use Plex primarily, but use Jellyfin and keep it patched just in case. If there’s any kind of ugly action with Plex, I feel like my bets are pretty well hedged. Plex definitely has a lot more polish than Jellyfin, but I wouldn’t doubt if there is a rug-pull in some way or another. After all, Plex sold a bunch of lifetime subscriptions ONCE but they still end up paying to support those. Sooner or later they are going to want more money again.
