If it were up to me I would probably go all scorched earth on everyone who supported Sun. Good thing it's not up to me, as you are quite correct, the optics of only burning SINMS is likely a much smarter move going forward.

Think about it this way: we could burn 70M coins and piss way less people off... or we can burn like 80M coins and piss a lot of people off. The risk vs reward does not favor burning more than the SINMS.
