Article’s kinda crap, really; the whole point is “a prick hired a prick to be involved in a prickish game.”
Ken Williams has generally been pretty well regarded, especially by Sierra fans. He was even included in the old Hackers: Heroes of the Computer Revolution by Steven Levy, so I think it comes as somewhat surprising that he was so easily swayed by Rush Limbaugh back then, and shifted so far right wing to the point of purposefully working with a cop so heavily associated with systemic racism and the Rodney King beating.
It certainly was news to me, as someone who grew up with those games.
