Simple aesthetic changes and codes of conduct / political alignment for contributors are not enough for forks to become full things of their own. Even if they can help (branding, community, etc.). Or hurt (Forgejo is harder to pronounce. And CoC have potential downsides, possibly excluding good people, ironically, over banal minutia and hostile environment around being "not hostile" - like you saying he is "hung up" on it...).
Gitea was already a fork of Gogs, so why should contributors use this fork of a fork?
These forks (and direct clones) are like little political secessionary/independence movements, both making lofty statements and splitting would-be contributors. Sometimes it works out very well and they become full independent things of their own (GNU stuff), but it's fair to want to get on to see the actual engineering side of things.
