I am coming to this from a perspective of a worker who used to get quarterly options of the public company I worked for, and I just cannot for the life of me sympathize with a company complaining that it can only afford to gather the information to calculate the worth of the stocks they are paying me in two times a year. I don‘t care how much it costs them. If you are gonna be paying and trading in stocks, I expect you to do the work required.
I understand your view, and agree that transparency is good, but "the work required" is largely preventing and defending against lawsuits by plaintiff lawyers, and those lawsuits cannot possibly benefit the shareholders (because whether the suit is won, lost, or settled, the money all goes from one pocket to another, with a cut going to the lawyers).
