We've had open source CI. We still have it. I remember ye olde days of Hudson, before it was renamed Jenkins. Lotsa orgs still use Jenkins all over the place, it just doesn't get much press. It predates GHA, Circle, and many of the popular cloud offerings. Turns out CI/CD is not an easy problem. I built a short-lived CI product before containers were really much of a thing ...you can guess how well that went. Also, I'll take _any_ CI solution, closed or open, that tries to be the _opposite_ of the complexity borg that is k8s.
