Sure, I know a lot of projects have been on GH since before MS bought it, but they’ve owned it for quite a while now, so we really should be seeing better migration out by now, no?
Codeberg is nonprofit which seems more in the spirit of the Linux ecosystem overall. GH is for-profit…
All these projects for sure are cloned on multiple backups, if something happens and github is no longer viable it is a minimal effort to clone the source code and bug tracking and move it somewhere else. Serious projects will have contingenties in place for this, lesser projects will do what the big guys do
