An unchanging community is a dead community, period.

Attempts to "preserve" a community, both online and offline, tend to end up preserving unhealthy power dynamics within the community as well, which would have been slowly replaced with something else if you had just let the community evolve (or disappear) naturally.

Often, members of the community who benefit from the status quo are the ones who cry the loudest for such preservation.
