Approx:
Entropic is engaged to make hw. I am asked (unofficially) to do sw.
Entropic works for free but does charge for parts and subcontracted stuff . Eventually defcon stops paying. Entropic is uninvited from badge talk. Their logo is ground out of plastic case. Their logo hidden in publicity photos of pcb.
Tempers are high. I implement the Easter egg. This is months ago cause thats how long one needs to pre-flash chips.
Time passed. Defcon still working on their game last moment. They had volunteers reflash badges cause they didn’t make the real pre flashing deadline. I forgot about the screen entirely more or less.
Day of con. I spend all day helping debug badge issues. Push updates. Help people. Even pushed an update from plane on way to con to fix some things.
Badge talk time. Half an hour before defcon tells me no talk for me cause someone found the Easter egg screen and they are pissed. I show up anyways since it was promised.
I get dragged off stage.
I hold talk outside answering questions.
Next steps: I have no contact with defcon. They never bothered to. Normally: who cares? I get to talk, people get to play with badges. Nobody cares.
But… I got kicked out, and… they have no license to my firmware they are distributing. Likely DMCA notice.
