Speaking as a semanticist, it's wild to me that they are phrasing it in terms of whether an *act* is characterized as "official", when what they seem to actually be talking about is whether there exists a *description* of the act that can be characterized as "official".
They seemed to deliberately avoid defining or giving Alexa’s of these “acts,” while also insisting (in this and other arguments) that they aren’t interested in hypotheticals.
