Interesting - There's a couple of things that I disagree with here, but I do think this resonates: "We all agree with the diagnosis and strategy: stop building new things, bring stability."
Where I have a problem with the positioning of their GitHub profile is, he's the CTO of GitHub, arguably the defacto standard for open-source version control systems. His GitHub profile is linked to as the author for the post, and his GitHub profile simply tells me: "this guy doesn't code."
I don't care if this guy doesn't work on GitHub itself, I hardly would expect that, but IMO, any CTO of a company like GitHub should eat, breathe, and sleep code. He might, but his profile, which is being published as if it means anything, tells me he doesn't.
