The point of GitHub is not technical - the website is terrible. It's the social network.
It does break and go down; and GHA are a real pain in the ass. But the basic hosting and PR workflow are fine.
It's still getting things done, for sure, but no longer pleasant to work with.
That's the real problem with Github these days. Too much critical information behind throbbers that take their sweet time. I find Codeberg much more responsive, despite being an ocean away and having the occasional anti-AI-scraper screen.
I help with one of the most popular projects on Codeberg, Fuzzel. I can say we get no shortage of issues and feature requests from being on an alternative forge. Indeed, we have plenty!
