Couple things here, Maro is a designer for the game, not the CEO. He has a very active blog, including a podcast during his drive to work. He regularly shares his opinions; often times stating when he is opposed to the direction of wotc/hasbro but it is vetted by management because of trade secrets. MTG is a very inclusive community because it caters to the fringe communities that are inherently different. They really don’t want to alienate their diverse fan base, they are a very expensive hobby that anyone can walk away from.

I am also going to recommend you actually read the article rather than a snippet/summary. He goes into detail about the user he was responding to is wrong, because he was unable to provide insight required for character building and how culture is whitewashed. This was not a push/PR piece he reached out to enlighten a user that was wrong. He is championing people to embrace diversity because it has visible value and gives examples. He is also doing this during an era of opposition which is when it’s most important. Maro is an amazing person that has done significant work towards all kinds of game development, I highly recommend checking out some of his comicon panels.
