I disagree, I am more likely to hier the guy after reeding this post as I want someone to know when they need help. And more importantly be willing to speak up.
I can't imagine anyone having run a company say they'll hire this person. Whether this guy was right or wrong is subjective, and people have opinions, but this type of attitude is so obviously toxic that this is almost a pattern.
There's a huge difference in someone who tell the truth to the one who needs to hear, and someone who posts it on one of these medium posts hoping that they can hurt them somehow.
