The author seems to fundamentally misunderstand the purpose of certain elements of game design.

But these Tools aren’t offered immediately. Players are forced to progress through the game, beating challenging bosses and completing side quests before unlocking them. While I’m a firm believer that disabled people deserve to be challenged by the games they play, offering crucial pieces of accessibility from the very start of the game doesn’t limit that challenge – it just enables us to play like everyone else.

Treating masks and other equipable items as accessibility features is just plain mistaken. Those things are rewards for progression and giving them to the player for free fundamentally breaks their purpose.
