It’s the confusing mess of subscriptions and seemingly locking basic functionality behind a paywall that’s skeevy, not paying for software itself. I have happily paid for software before and would again. Plex has never appealed to me though, and they’re certainly doing nothing to make themselves more appealing.
Be that as it may, the Plex official guide for setting up “remote streaming” walks you through port forwarding. That implies that when they say remote streaming, they mean port forwarding by default. I then had to go digging to find mention of the Relay service which seems to be a fallback. (Apparently it isn’t even supported by all clients)
Surely if they meant they’d start charging for Relays they’d mention that explicitly, and not use the term “remote streaming”?
