Move where exactly? Bitbucket and GitLab aren't that great either.
I'm affected by GitHub outages maybe once every 2 months for a couple of hours. Sure, various parts go down but it's never something super impactful to my workflow.
I am not particularly keen on github and microsoft scraping my code and re-selling it via copilot. If you own mission critical ip you can always spin up a vm and setup reliable backups using gitlab, or simply via ssh. It really is that easy to move away.

It's not great but, IMHO, not outrage worthy.
