In other words, nobody can possibly have been correct, only lucky.
No. In other words, we lack the information to know if anyone was correct. Maybe BryonD was correct. Maybe WotC was correct, but something nobody could see affected outcomes. I'd more likely guess that "correct" doesn't apply - the information available at the time was not sufficient to make a reliable prediction.
More relevant in our own little space here - getting into each other's grills over speculation is kinda dumb.
Calling people "apologists" for not agreeing with you is also pretty danged rude and dismissive. You might want to rethink that particular tactic.
And, of course, WotC couldn't possibly have been incorrect (even with their vastly superior access to information useful in making the decision), only unlucky.
"Vastly superior" compared to what? Our "nearly none"? That's not saying much. I try not to second guess those with superior information, but let's not make that to mean that having more means they actually had enough.
You speak as if there's a "right" and "wrong", a clear correct and incorrect in business - like business was a deterministic, predictable machine. I think very few who look at the business world would agree with that. Business isn't about knowing exactly what will happen for sure, but about managing among uncertainties.
This doesn't mean that you cannot criticize business decisions, but it should impact how you do so. Set aside the idea that anyone is objectively right and wrong, and look at whether, given the information they had at the time, and their goals, what they did was wise or unwise.
Don't know what information they had, or their goals? Well, then criticism becomes more difficult.
