You are just assuming, that MS actually knows and cares for what users want. In my experience its the other way round. MS will introduce a change/new behavior and user have to adjust their own behavior, because most are not willing to switch to a competitor program.

I remember very well how much my father sweared at the computer because MS changed the UI to the ribbon bar. It wasn’t at all what he wanted and MS didn’t care to ask users beforehand.

In the way it is phrased I would second this. The problem is, that it faults the disabled person for the life problem of those around them (THEY are ruining other peoples life). The discourse never ever blames the disabled person here. Doing so will land you in a bad discussive corner - together with the common argumentation of nazis. Though the question of abortion (as stated by OP) is not as clear cut.
