I don't really see the appeal besides free hosting + some storage.
People should either self-host a gitea/forgejo/gogs server for like 3$ a month on hetzner or just use gitea.com.
If you want to share your repos, just use sharemygit.com and spread the repo on coding forums. Personally I find this a much better stimulant for a community, then just having free-flowing code spread around like dust under a bed.
+ you actually dont need to be the victim of the whims of some ideological git-server provider. Ahem github (master->main), codeberg (no private repos are allowed), gitlab (you have to pay) etc. etc.
