Dmitry has repeatedly stated he was not hired by Entropic nor was asking to be paid for his work. He did it for fun. I'm not sure where this misunderstanding is coming from.
Does sound like "asking to be paid", even if it's then switched to "it was all a prank, bro" when it turns out that wasn't the greatest idea.
The reports I've seen have said "Go to the about screen and press the select button". That's not difficult.
