There is an interesting caveat to all of this, however. If what you say is correct, then such behavior can actually be reported to Patreon as mis-behavior. Since 2018, Patreon has gone to great lengths to force developers to include accessible options for disabled patreons in their options; placing a site wide ultimatum that all offerings on the site, must be disabled friendly at the very least. This comes out of a lawsuit which Patreon settled, where it had been found that the site wasn't enforcing their own accessibility rules. Patreon lost the case, agreeing to settle out of court, with part of the agreed upon change being strict adherence to their own accessibility rules for both developers and content presented on the site. Part of those rules hold developers accountable for off-site behaviors, such as the developer here (if true) stating disabled people don't deserve to play the game.
Patreon's usual response, if evidence (screen shots of statements, and so on) is provided; is to freeze the patreon payments of all developers of a project, until such time that they submit a disability friendly update, or version of the game. They also begin to regularly spot check the behavior of such developers, with a note being that further action can result in the person's entire patreon being closed and funds returned to the people that paid them.
So, if what you're saying is true, and can be proven; then the developer is playing with fire and risking someone getting pissed enough to report them for their ableist behavior.
