Not to mention all the startups being founded right now. Sure, github's still the default, and maybe you can still monetize stars or something, but it's also a clown show from an availability, feature roadmap and company policy perspective.

Is it really fiscally responsible to tie your company's future to that?

I wonder if anyone tracks metrics for this stuff. Percentage of stuff with a repo there is probably still high, but what's happening with stuff like github actions, and are devs directly pushing to github, or are they just mirroring an internal / other provider's git repo to it?
