GitHub is the new Internet Explorer 6. A Microsoft product so dominant in its category that it's going to hold everyone back for years to come.
Just when open source development has to deal with the biggest shift in years and maintainers need a tool that will help them fight the AI slop and maintain the software quality, GitHub not only can't keep up with the new requirements, they struggle to keep their product running reliably.
Paying customers will start moving off to GitLab and other alternatives, but GitHub is so dominant in open source that maintainers won't move anywhere, they'll just keep burning out more than before.
