This is awful advice. Simple and elegant design does not start with dismissing potential problems.

Those questions are all prompts to have a discussion in lieu of tech trivia hour. Those responses do not demonstrate wisdom, they reveal a lack of maturity. It's not the interviewers fault you refuse to be interviewed.

I agree, the responses give the vibe of "your questions are dumb and I'm too smart to waste the effort to engage with them." If you don't want the job, then don't interview!
