Most of the WTF feature releases are rolled back or deprecated within a few releases. So the community tends to be right on with what Plex should be doing. There's a lot of pigheadedness on the engineering side it looks like.
I also agree the lifetime pass was a bad business move. I think a better model would have been something like "pay $45, get every release in this major version, new major versions come out approximately every year" or with an alternate tier that would be "use plex, pay $35 per year, get all the updates". It would have smoothed out revenue and focused development on paying customer demands.
