But the article's exact wording is "Sustkever is said to have offered two explanations he purportedly received from the board" key word being "purportedly received". He could be choosing words to protect himself, but it strongly implies that he wasn't the genesis of the action. Of course, he was convinced enough of it to vote him out (actually; has this been confirmed? they would have only needed 3, right? it was confirmed that he did the firing over Meet, but I don't recall confirmation that he voted Yet); which also implies that he was at some point
told more precise reasoning? Or maybe he's being muzzled by the remaining board members now, and this reasoning he "received" is what they approved him to share, right now?
None of this makes sense to label any theory as "most likely" anymore.
