I’m going to be way more strict about confidentiality with an interviewer I don’t know at all than with a trusted colleague. For all I know you get beers every week with the CTO of my current employer’s largest competitor. Besides which there’s a way more interesting variation on the question, which is “how would you design our product?” Got that one in my last big tech interview and quite enjoyed it.
