Where does GitHub even make most of their money? Their compliance posture makes them a non-starter for any regulated industries (which is atypical for a Microsoft property, generally MS is the market leader for compliance in all of their products).
Given that a lot of places that deal with money use them, I find your comment quite interesting and would like to learn more :)
Places might be officially regulated, but neither government agencies, healthcare, finance or defense industries are as strict as you think. People have to get stuff done, and most are usually quite incompetent in these protected industries.
Microsoft’s sales reps know this.
