Of course you're right that it isn't right to blame all of them as I did. But it's my personal opinion that a lot of people in management positions try to go the "safe" way. Nothing wrong about this, but in fact they don't decide they just follow the masses. Thats a general problem not just in programming. They are paid to find good solutions, but they just try to reduce the risk of their decisions and take the average solutions. That can be extremly annoying.
