CNN interview questions

A senior management recruiter reached out over LinkedIn. I was honest in my reply that I wasn't actively looking but am interested in learning more about the position and company because you never know. I never got a response back. I understand it would seem like a waste of time to talk to someone who wasn't actively looking but ghosting a potential future candidate just seemed short-sighted. This encounter does not change my impression of the company, just perhaps I thought a senior recruiter would show more professional patience and manners.
