I know a lot of folk that work at MS or have worked there, they are all very good people. They are highly motivated professionals that are top in their field. MS is a rich company and they recruit the best they can. However those are not the people making any kind of decisions. And it's a cut throat company, if the budget gets cut, you are out on your ass. At least in most of the world, where strong employee protection isn't a thing.

Don't get me wrong, MS has a lot of bad apples just like any other company. Useless managers who say dumb shit and take praise for other peoples work. A leadership that doesn't care about anything except their bonuses and the bottom line. But at least as far as the engineers go, there's plenty of really good folk.

People also seem to forget how huge MS actually is. And a lot of the time the different branches within the company are as far away from each other as can be. Even within the same branch one can only talk to so many people.
