According to DC: they scrubbed their name from a component of the badge Entropic had no part in creating; they retained Entropic's name on Entropic's actual parts.

OK, but also didn't credit them in any of the communication about the badge, uninvited them from the badge talk, and uninvited the firmware author when they found out he'd put credit to them in the firmware. Really isn't looking like they were keen to give credit.
