This headline is misleading. If the owner of the server has Plex pass than the users can use remote streaming as normal. If the owner does not have Plex pass, then the users need Plex pass to use that server remotely
Imo a stupid move by Plex, but as a lifetime Plex pass holder, no one that uses mine will have to worry so I'm relatively unbothered.

As long as you have Plex pass it's all good and nothing changes. That said, this was exactly my reaction. Plex expends exactly zero fucking resources for my server, so wtf is this shit supposed to mean?
