The thing that irks me the most is not the practice itself. My problem is with everything else in that post.

Note that he has not described it as a morally ambiguous but sometimes unavoidable choice (like you did) but as the most righteous and noble option. That he's openly admitting he knows that it's illegal. Pay attention the sugar-sweet language of his parable and how its tone gets more colorful whenever the story takes a darker turn (from pov of the employee).

I mean, this entire thing is something out of a dilbert strip. I'm serious. This is something you'd expect Dilbert's CEO to write. The self deceit, the contrast between the language of "hurt feelings" vs the unstated reality of a person getting fired as a consequence and the stupidity of it all are mocked in hundred different Dilbert strips. Remember when this wage fixing story surfaced and the surprised comments that they were stupid enough to put it in email? If Mr Horowitz ever gets in similar trouble the paragraph i quoted above will make these troubles a lot worse.
