Why would they find another project? Are you under the assumption these are not established members of the Nix community complaining, but some "invaders" as alluded to in the RFC 175 supplements? Because that's untrue. Many have been putting up with the deteriorating situation for years, very stoic, but not healthy or fun.
There's a difference about "starting anew" and "forking." As I mentioned, many projects have no option due to licensing changes, but they should try harder to fix the personal issues.
