This was before Actions and a whole lot of other non-git related stuff. There was years (maybe even a decade?) where GitHub essentially was unchanged besides fixes and small incremental improvements, long time ago :)
GH Actions was good for them as another billable feature, but I'm skeptical we actually gained much over external CI providers
The improvements to PR review have been nice though
Back in the day when software could be "finished". Ahh, the good 'ol days
