Every community is the sum of its members. Each person who joins changes it, at least a bit. And each of those members is changing and growing.

When community members have different needs, forking should be a last resort. It's expensive, and it's wasteful unless two different groups have irreconcilable needs. It should only ever be suggested as a last resort, after other options have been exhausted.

However, it's often used as a first resort to shut down criticism and to protect existing power structures. The person who speaks up is, as here, treated as an outsider and an exploiter.
