...you're missing the point. WotC explicitly said they will try to be more culturally sensitive with their products, and therefore it's hypocritical of them to continue to make money off a book like OA. whether or not they remove it what matters is they, the company who owns the rights to it, no longer make money from it.
That is disingenuous, as that is not the point.
The original tweeter explicitly (emphasis as in yours) became more agitated when the price was lowered (therefore, less profits).
And, when someone said that it should not longer be sold at all, and instead be free (NO PROFIT AT ALL), Mr. Kwan was completely incensed:
"You think making a racist product even more accessible is better than removing it?"
In other words, despite the people claiming falsely that this is not a call for a ban, this is, in fact, exactly what is desired.
This point has been made repeatedly, in multiple threads. Now, if you are in favor of banning (removing something completely) a historical product that now causes offense, that is fine. At least own it.
