This didn't happen.
The passage in the history book didn't "disparage the creator"
Wizards of the Coast wanted to "call out" controversial language in its new DnD history book, The Making of Original Dungeons and Dragons.

OG D&D included an insult the entire concept of equality for women. The history book mentions that.
Reality exists. To not recognize the reality of sexism in the game we grew up enjoying would require a rewrite of history. Including that history is not a disparagement of the creator.
This weird demand to deify E. Gary Gygax is weird. He's not a God. And presenting his words isn't an insult towards him, his children or his family.
We've all done and said things we shouldn't have. For we are not perfect.
We shouldn't expect a game creator to be perfect either.
