Why is it generally accepted that recruiters can ghost people?

For anyone else it's incredibly rude to just ignore messages from people, but for recruiters it's just expected.

Call me naive, but I think its incredibly unprofessional and a bad look for prospective companies. I understand that recruiters can be overworked and not have enough time to answer people; but if that's the case, the company should higher more recruiters so that they can answer everyone (I mean that's their job isn't it?).

I would much rather be told "We didn't choose you" then have to wait two weeks, search LinkedIn and guess which hiring manager was the one I contacted, message them about my application status, and then still not get any response.
