Why do employers ghost an applicant?

I have seen this happen multiple times. You can’t have the courage to let me know your decision?

OK some people here are misinterpreting what is happening. I didn’t just apply. I was already in contact with them by having an interview.
They cut off communication after the interview, which is extremely unprofessional. I’m not saying every applicant should be reached out to. Good God
