I can say that I've chosen not to bother when submitting a fix requires me to stray away from GitHub, and doubly so when it doesn't use a PR/MR workflow. There are only so many hours in the day, and I don't have the patience to deal with unconventional workflows when there are other things I could be doing with my time.
For projects that I'd be interested in being a long-term contributor to, this is obviously different, but you don't become a long-term contributor without first dealing with the short-term, and if you make that experience a pain, I'm unlikely to stick around.
A big part of this is the friction in signing up; I hope federated forges become more of a thing, and I can carry my identity around and start using alternate forges without having to store yet another password in my password manager.
Sad we're at a stage where people don't contribute to free software projects because the service it's hosted on isn't the proprietary, corporate giant.
"Friction in signing up" being a big part for you is also weird, considering basically all free software GitHub alternatives (Gitea, GitLab, Forgejo) support SSO via GitHub.
Just checked, and it looks like my GitHub account is not linked to my Microsoft account, nor does it have my phone number.
I just signed out and started the signup flow. It allows me to use an email on my own domain, and I got as far as verifying my email before I canceled the flow, and there hadn't been any requirement for phone number of Microsoft account yet.
