I think - at least for the people who stick with a career in PR - that they enjoy playing the game of giving an answer that is sort of related to the question but doesn't actually give a single bit of useful information. That they enjoy seeing how far they can push it without the interviewer straight up accuse them of not answering the question.
At least that's the only way I can imagine them keeping their sanity.
