I've seen a few organizations consider moving from ADO to GitHub (only repos and CI/CD pipelines) due to the new fancy AI features, but this frequent downtime has been a constant in meetings.

ADO may be stuck in time but at least it works.

Source Hut has been around for 6-7-ish years (https://sr.ht). A rather different approach to Git, closer to its original intentions. No PRs in the classical sense, just email patches (that's how the Linux kernel is developed to date). You can do most things though that you can on GitHub using tools and CLI.
