Is anyone even using CC?
Apparently quite a few people are. I'd guess though that the majority are opting for the complete CC suite, and not the standalone version. Also, I'd guess that the whole thing has swung towards what might be described as 'corporate' use since, as you say, it's not exactly an enticing option any more as a rental (thanks a bunch, Sarb-Ox), especially for a single app.
What I do know is that the developers are aware of this issue, very much so. Unfortunately though any decisions about it have to be corporate, and accordingly how much pressure can be bought to bear over this - well that's a bit moot...
