I do that every time a recruiter cold calls me about an opportunity without mentioning the company, if the opportunity sounds interesting.

It takes like four seconds.

Who would bother to find out who the company they would be working for is? Who wouldn't?

I do that to find out who the company is. It's usually a better way to find out how much they pay than the recruiter is. Too often recruiters try to avoid telling me either item.
