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.
If you use one account and buy everything with one account and are always signed in, you're fine.
If however you order something and use your email address but are not logged in, you get your invoice and tracking to your email address but that order does not appear in your account, and if you go to the website/app and try to use it to track your order/respond to seller messages/whatever, you can't find it there. You have to go to a different page, a link in the email, and "claim" the order with your account.
Oh, also, if you aren't logged in and use a different email, a different account is created, based on that email, and the order is... half-claimed to that account, meaning you can't claim it with your actual account unless you jump through some hoops. Otherwise you can create an account with that half account to track that one order, and there's also no way to transfer orders without contacting support.
Also, if you use PayPal and aren't logged in, they just go ahead and create an entirely new account without a password, so you reset the password to eventually track that order, and all the other issues above.
I have something like four etsy accounts now and I've never seen a website make such a dog's dinner out of something as otherwise straight forward as accounts.
