Downvote me to grey-world if you like, but I think everyone's crazy to put all their code infrastructure in the hands of fucking Microsoft. Especially literal free open-source software. Who do you think Microsoft is? What do you know of Microsoft's history and their core values (they're "embrace, extinguish & exsanguinate"). It's like giving fucking Sauron safekeeping of your power-rings in Mordor, oh we have great infrastructure for safe ring storage here, very secure, the orcs are really expert guards.
