Earlier quoted context omitted.
> IMO it is understandable that fixing some piece of proprietary software is not a top priority. I believe it's more appropriate for the author to rant against JAWS for not caring about QT, than the other way around. Worth pointing out, JAWS is proprietary, but it is also very widely used. I'd imagine its user-base is many, many times that of NVDA (which is the open source equivalent).
Yeah sorry about that. Maybe "some" seems a bit too careless. Not intended that way. Substituting it for "the most popular proprietary screen-reader software" still doesn't change anything on my opinion though :)
So, yes, open source programmers are perfectly within their rights to ignore that audience, and that audience is perfectly within its rights to not use open source software that doesn't meet their accessibility needs and to warn others and advocate against the use of such software.
