It's his fault because he accepted the price for his business! He was in numerous conversations where people wanted to invest in WoWork and he told them that the valuations they were investing at were not just reasonable, but under the real market price - which is why venture buys into companies.
> none of those events actually materially impact the value of the business
> overnight, investors just came to their senses about what kind of value this type of business is worth
These things seem like they contradict each other. If Neumann's actions are not material, why did his removal reveal the true value of the company? Material just means it changes the value of the company. There are lots of "material" events that don't have anything to do with business fundamentals.
