Does providing feedback make this effect worse, or better? How do we know? N=1 isn't exactly a significant sample size.
It used to be common knowledge that doctors should never say they're sorry, for the same reason (fear of lawsuit). Then research showed that apologizing actually reduced the number and severity of malpractice lawsuits.
I see plenty of people attacking tech company interview processes on social media already, without being provoked by honest feedback. I'm having trouble imagining how feedback could make a person more angry.
Engineers can't even go through a code review without getting butt hurt. And that's when you're on the same team with mostly the same goal.
Usually the blowback to the company hits marketing/legal/HR. Gathering and delivering feedback takes work. It's really politically expensive to explain why you're going out of your way to do work to cause other departments to do work for the sake of tech community altruism, especially right after it just burnt you. Giving career advice to strangers after an interview isn't the norm in any other field.
I don't really care if the candidate tries to sue the company. I don't work in legal, that's mostly not my problem. But if legal doesn't want to deal with it and ends up being a pain in my ass, yeah, I'm dropping the practice.
