Yep. But again, it’s really not clear in this case if DEFCON was paying their vendor (EE) for software at all. I can see how it was ambiguous from their side given Dimitri was friends with the hardware design company. But from the POV of Dimitri and EE, DEFCON was paying for hardware and a separate 3rd party (Dimitri) volunteered to write the software. It’s very spicy to attack people in your community who volunteer their time.

And unpaid programmers doing cheeky things with code because they want to is the heart of DEFCON.

I can see where DEFCON is coming from with the calls they made here. But it’s a mistake to treat Dimitri as if he were a vendor. He's not.
