What would it take for you to move away from Github?
Let's be honest, the majority here probably has a github account. Some of us are happy as a clam and wouldn't switch no matter what happened, but there are some who would and haven't yet. Why?
People didn't move when it became a social network, when Microsoft bought it, or when their IA scanned the whole code to make money from open-source projects. Only Musk buying it would change that a bit, but it still wouldn't not destroy it.
As for me, I don't have an account. My personal projects stay private, and for work I have pro accounts at GitLab or Azure DevOps.
