I've never seen Plex users argue in support of Plex. only comments along the lines of, "I use it because...."
the jellyfin users are generally the ones getting bent or upset because people still use Plex for their own personal reasons. they then accuse the Plex users of not contributing to jellyfin because they still use Plex. "if only you used jellyfin, xyz feature would be magically finished because you are a part of the community!"
point is, the only people arguing here are jellyfin users. Plex users are gonna Plex.
