I think the hostility is understandable when you consider that blind and other disabled people, like myself (I'm partially blind) and the poster of that comment, live every day having to work around widespread indifference toward our needs. I'm not immune to it myself; see some of my older HN comments on GUI toolkit accessibility, before I started AccessKit.
