Perhaps the reason those ObjC fans of the language itself seem to be smaller in number by your metric is that there are other reasons for avoiding GNUStep--namely, that it's GNU. If you've grown up with OSX etc., then you're more likely to be BSD type person (thinking primarily from a licensing perspective here), and the FSF's push viral "software freedom" is a big turn-off.
