I do, and through conversations have learned that they enjoy what they do and publish patents (they're PhD in industry), but ultimately what they seek is "fame and glory" (literal quote).

I was also in academics myself up to the Master's level (research track), and personally had to deal with the politics of getting support for what I wanted to work on; that experience helped to discourage me from going on to a PhD, as I'd rather have proper leeway to work on what I really prefer and take avenues I find interesting.
