Thanks for your great wording, John.
I belong to this category (somewhat). I stopped contributing because I felt that my work is not adequately supported. I felt the need to develop some software. I have rather limited free time however, and I've been in the "not highly productive on-wiki" phase for over 3 years now.
Incidentally, one of the entities that doesn't adequately support my work is my local chapter. It had been extremely hostile toward Wikimedia movement and after learning how it works I had no motivation to continue working with Wikimedia projects. How poorly the Wikimedia Foundation itself works wasn't the biggest obstacle (I found it mildly approachable and was (and am!) a tiny bit happy with it).
