Oh my, #DEFCON. Supposedly stiffing the folks (Entropic Engineering) that did the hardware design for the badge, removing their logo from the casing, dragging Dmitry Grinberg, the firmware developer off stage, because he hid an easter egg in the firmware asking for donations to the hardware designers. That's, IMHO, quite low, to put it mildly. More context at https://www.reddit.com/r/Defcon/comments/1eoe4u7/comment/lheaj3b/
