Maybe. Those are not clearly indicated as mistakes either (i.e. the article does not demonstrate or even argue that another choice would more likely than not have led to a better outcome). And the article conveys some justification for the choices that did get made. For example, they couldn't use certain "second tier" Ethereum features that would have reduced gas fees, because they aren't approved in states like New York? So maybe you argue that such features should have been used, but then you're optimizing for a different outcome -- the outcome where you don't win the auction. With the benefit of hindsight, sure, but the leaders didn't know before the auction that they would lose. So it was certainly a reasonable choice to take the approach that seemed most likely to raise the most money.
