Self-interested fork
A self-interested fork is one that does not advance common values as defined by any faction in the political spectrum, but only advances the common interests of those participating in it, and their competitive or reputation position relative to others.
It often occurs just because a creative network gets too large and politics as usual interferes with keeping the group working together with consensus.
The self-interested fork problem arises when these are too easy to create, and when the creative networks are not therefore required to cooperate to make an effective power network that could advance the overall project in the real world.
