Feedback is not a reward. It's a way to improve processes, and if we as a group give feedback then we as a group benefit. That recruiter might move on to another company, and you might benefit when you interview there next. Or you might benefit from someone else having given feedback to a recruiter at the next place you interview. Or it could come back to you in myriad other ways. The idea that it's only worth doing things with a direct and immediate benefit might appeal to some people's Randian insensibilities, but it's really quite broken.
