You think it sucks because you're used to GitHub's interface. I really dislike the github interface after having left it a few years ago. Gitlab's interface is, to me, so much better and a breath of fresh air (even though it might look like the old old Github).

As for forgejo, I agree, once they get functional federation and a good CI (not a shitty Github actions clone), github and Gitlab can really fuck off. Gitlab might become a "competitor" once they have federation, but they only will do that if forgejo takes off sue to federation.
