Don't know about that; I worked for DevDiv in 2008-2009 and it was the most spectacularly dysfunctional island of not-invented-here inefficiency I have ever seen at any point in my career. They imagined the tech world to consist of Microsoft at the center, where all the smart people were, surrounded by an ecosystem of ISVs, all of whom wished they could work for Microsoft instead if only they were a little bit smarter, and then, out on the fringes, the barbarian wastelands of pain and misery, where incompetent nobodies struggled with trivial legacy projects involving esolangs like COBOL or Python or Ruby. A more self-absorbed computing culture I have never seen, utterly incapable of recognizing, much less learning from, any "innovation" generated outside its own walls.

Perhaps they've improved since I left, but the number of dev-hours I saw being squandered on a daily basis just fighting with utterly stupid limitations which only existed inside DevDiv's idiosyncratic tooling would have funded a good hundred startups full-time if they could have been put to some practical use.
