I don't have any knowledge about nix, the community, about Eelco Dolstra, or about this particular drama. What I do know is that there is no such thing as "community leadership" and that extremely long diatribes about the flaws of the founder can be safely ignored.

People who are unhappy with the community or the direction of nix should leave and start their own thing. They'll discover that building something is actually a great deal harder than it looks from the outside.
