The taboo of discussing salary is just a tool to keep the employees in the dark, so that it's easier to negotiate with those who are less market savvy.
I have also heard the reasons why it is "also good for the employees". Like, "what if you are more productive than your colleagues, and you get a higher salary than them, then they would be jealous of you, and it would make the workplace interaction awkward". Yeah, pull the other one! In real life, if you do similar things, the differences in salaries are random, depending on negotiating skills, and the market situation in the year each employee was hired. And, of course, geographical location; the most important job skill is to be born on the right side of the border.
> post a low offer initially, and gradually raise it
If you do this publicly, the people who accepted the initial offer will notice they made a mistake, and will either ask for a raise or start doing interviews with other companies.
