Yes, counting users tends to be fuzzy but Fedora has published some statistics which provides a good estimate. If others do too (along with smolt profiles), we would get a better understanding of our user base and use that to convince vendors and ourselves to support Linux better.
I am sure there is a agenda involved in getting commercial vendors involved to participate more which I think is a good thing. If there are accusations of anything else. being explicit is (somewhat) courteous. I don't see anybody mentioning "evil". Debian contributing as many patches as it has as a volunteer based organization seems pretty remarkable to me neverthless.
