Earlier quoted context omitted.
On my team our downtime is very closely correlated with how much we're working and changing the product. I'd be surprised if GitHub is much different.
exactly. Before M$ there wasn't much product movement at Github :/
I've heard that for a number of years the Product org at GitHub essentially considered the product "finished", and that it did not need more features. Things like the rise of GitLab and the "Dear GitHub" letter, plus I believe a change of leadership, helped that completely turn around. Obviously that took time to yield benefits, so I think they've been in a much better place for quite a few years now.
