> If your requirements for joining a tech org are that you expect them to have made all the same decisions you would have made if you were in their shoes, without error, then a) your bar might be a little high and b) what the hell do they need you for, they’ve already got a team that can do everything you could bring to the table.

Maybe they have a team that can do that, maybe they don't. Figuring that out is (allegedly :-) ) why the interview is being conducted, and it's definitely not something that can be gauged based on nothing but whether you ask a "why" question or not.
