As I worked in amazon previously and know this first hand, you can translate it to: "Shut up, and do as be told". It is a very top down hierarchal type of company, and engineers usually have little influence in general, and often are kept in dark on key decisions. Disagreeing in general is seen as a nuisance. A lot of it would disappear if managers gave concrete details on why a decision was made, but it usually takes a skilled manager to do that, and Amazon, as a large company, has a combination of good managers and plenty of not-so good ones.
