I'm not sure I understand the need for charging to play media on a private server when not on the local network. Why is this no longer going to be free? I'm glad I bought a lifetime pass many many years back but I definitely wouldn't pay for Plex nowadays with alternatives being comparable. What a silly choice they made~
I’m not defending them because it’s a shit move, but they clearly understand the most valuable feature is not their ad-ridden free content but rather the original value prop of the service to make it easy to share personal media with small groups of friends.
