You lament the decision by FB yet you say out of the hundreds of managers you worked with only two were good. You are saying most managers aren't good and it sounds like FB agrees with you and hence decision. I also think this might be a good decision because I do think managers need to be able to set up programming environment and at least be able to navigate the code. Kinder of like how some retail companies make head office staff spend some time at a real store so that they are aware of operating environment at the coal face.
