So yeah there are people who genuinely believe that "accessibility" means only making things that are unchallenging. This is incorrect in any form of art, whether it's popular media or something more traditional. Accessibility in writing means printing in larger text, use of readable fonts and formatting, translation into Braille, and recording in clear audio. Accessibility in gaming should mean colorblindness filters, toggles to deactivate strobing in cutscenes and environments, scalable text, custom keymapping, and the ability to modify graphical settings including framerates, motion blur, fixed versus free camera, and so on.
To truly engage with any form of art, one must at least be willing to be challenged. To claim that challenge is by its nature inaccessibility is at best ignorance to the purpose of accessibility, and at worst a gross infantilization of people like me who actually have disability-related struggles that could be mitigated with some fairly basic control of settings.
