I read a lot of comments on HN about his response being unprofessional and harsh, and on the latter of those counts, I do agree, it definitely had a negative tone. What I want to know, though, is _why_ so many consider it unprofessional. To me, and I'm making the assumption that Yishan isn't lying, any pleasantries owed this man ended the moment he decided to not only publicly broadcast his employment, but also falsify details regarding his termination. Regardless of what I think, what actually makes this whole exchange unprofessional to others? Why should these details be protected, and why should companies and individual remain silent on these issues? I'm lumping this into the "political correctness" category until someone tells me it's about something more than someone having their feelings hurt (that they may have been asking for, even). Putting on my future-employment-perspective goggles, I can kinda-sorta see why this wouldn't be good, but I'd also be the type of person to argue that the current state of PR is particularly dismal when employers can't give any kind of factual details about a former employee's work record beyond whether or not they were fired. Why not just report details of employment and follow-up with the employee on any questionable/negative remarks? My guess is that a bad apple ruins the bunch when companies didn't/don't investigate those details with the employee and just pass them up altogether, creating an unfair situation for the prospective employee.
