These ad-hoc efforts are wonderful and extremely effective and are the utopia we all strive for.

Ultimately, I think, the distinction between "products" and ad-hoc effort is that one is tolerant of abuse and bad actors (the "enterprise" or bureaucratic system) and the other simply isn't.

I think I read it somewhere here, that any large project eventually turns into a moderation system.

I'm not sure what actions to take as a result of this observation... except perhaps to be a little bit sad.
