Frankly I do not find any fault with the drafting of the rule.
The problem was that someone failed to read it and implement it properly, and apparently that mistake was repeated up the food chain. Since such questions should have been anticipated and addressed ahead of time, that is a leadership failure.
The problem is compounded by the stubborn unwillingness to admit a mistake, even though everyone else involved can see it. They think that this goes away. Really they are just making themselves look foolish.
But when you have a monopoly, you can do as you please and leave everyone else scrambling to anticipate your next move.
My guess is that they will indeed issue some sort of rules change, so that they can lecture us about how WE had confusion and how THEY are going to be so wonderful in working to dispel OUR confusion. You know, the condescending, self-excusing approach that is so common to arrogant organizations.
