Looking through the commit history[0], he doesn't even look to be all that prolific as compared to other contributors. One would imagine those folks would keep on keeping on in some fashion.

Seth, to his credit, is doing what he can about his. Legally, there isn't much. But if a minor inconvenience--and it is minor because Chef is already busily scrubbing his name from "chef-sugar-ng", including removing him from the cookbook's authors, they can get their replacement just fine--alerts members of the Chef community to their ratshit behavior, that's a positive. Because some, who do not hold amorality as a virtue as is en vogue in these parts, will probably take exception to it, too, and they should know.
