I'm not going to pretend I can see the rest of the community, as I'm inherently antisocial. But I can tell you why I left.
I don't know about the other UI modders, but my leaving actually didn't have anything to do with the UI modding itself.
I played several characters. Each of them was fun until I finished the level 20-25 armor quests. After that... it somehow dried up. There weren't any interesting quests, even when I did sit through the voice acting on the dialogue. And the server population had passed me, so I could almost NEVER find a group.
Then SOE started messing with the game controls and being jerks about it: changing the defaults, and claiming the external camera recenter key breaking never occured. That was that. My account was cancelled anyway, but now I've basically decided I'm done with MMORPGs. And it will stay that way as long as I'm working the night shift, which I pretty much have been in every job for the last 2 years.
So, that's my story. Maybe you'll be able to find a way to connect the dots once there are enough.
