IMO the implication that the "in-person conference" nature of the forum is what led to its demise rather than its capture by academics/abandonment by industry practitioners is incorrect. I think a better summary of the cause is that most academic research is not that relevant to industry but academics need the prestige of forums like Usenix ATC in a way that industry does not which naturally leads to squeezing industry (and thus much of the relevance) out of the forum over time. I think the same would have happened to a virtual conference/printed journal/etc.
