gateway messed up with the b2 firmware, whether the code that does indeed exist was meant to specifically brick clones or not cant really be 100% proven, they did mention that they where developing a technique to prevent accidental updates, which could lead to bricking.....whether this code was one and the same, or it was indeed designed to purposely brick consoles, nobody really knows except gateway, anyone claiming to know is just assuming
yes the code does exist, and yes it is dangerous....as to why, your guess is as good as anyone's it does look bad but then so would a person standing over a body with a knife in their hand.......fact is you don't know the reasons so you cant say for certain how or why it happened. they might indeed be a big nasty evil murderer, or they where simply cutting their cake and slipped
