Almost nobody needs accessibility; let's be realistic, it's obviously not a priority. The priority is to put this out the door (MVP style).
this was down voted but its correct. even if as a human j disagree and it sounds mean, this is how people think in general..too bad, but too true. accessibility will come after 'launch'.
Unfortunately too many developers share your perspective. I'd be surprised if anyone building commercial software would move ahead without accessibility support though because, 1. it's required by law in many situations, and 2. it makes good business sense.
