We are also changing how remote playback works for streaming personal media (that is, playback when not on the same local network as the server). The reality is that we need more resources to continue putting forth the best personal media experience, and as a result, we will no longer offer remote playback as a free feature. This—alongside the new Plex Pass pricing—will help provide those resources. This change will apply to the future release of our new Plex experience for mobile and other platforms.
Wireguard so you are always seen as being on the local network. This bit of assholery is easily defeated.
Or morally better than breaking TOS, use a FOOS alternative like Jellyfin.
Nothing morally wrong with working around a artificial limitation.
