It wouldn't surprise me if that is at least order of magnitude wise correct.

My guess would be that OSMF members represents the minority of OSM data 
(corrected for large imports). Even if you assume that OSMF members are 
the most active mappers (which I am not sure is necessarily correct, 
just the most _politically_ active, which though probably correlates at 
least reasonably well with most active mappers), the shear number of non 
OSMF members will outweigh that. And the more mainstream OSM becomes, 
the less members of OSMF will proportionally contribute to OSM. At least 
that is my guess.

Of cause, my opinion is based on absolutely no evidence other than my 
gut feeling.
