It seems very likely that the majority of the 60,000 contributors you mention are there with the intention of building an encyclopaedia based on a neutral point of view achieved by verifiable information attributed to reliable independent sources and disseminated under a free licence. Since there are recommendations that would challenge every single part of that intent, it seems reasonable to assume that some non-trivial proportion of the volunteer workforce will not wish to continue to participate in a project that has so dramatically changed its entire raison d'etre.
