I agree with what you are saying, but I also have my own comments relating to such things.
What I had seen is that these use of banning words and using different words, mostly just makes it more difficult to communicate properly, rather than actually helping anyone. (Occasionally some specific change is helpful in some contexts, but often it just makes it worse.)
I think that all of these changes are rather excessive. Sometimes they do make an improvement, but often they don't, and may make it worse. Sometimes it is an improvement in some contexts, but it should not be applied to contexts in which it is inappropriate.
I also don't like such words like "visually challenged", etc. It is better to use words such as "blind", although it can depend on the context. Sometimes "unable to see" might be more appropriate (since, just because you are unable to see something does not necessarily mean that you are blind; e.g. maybe you are looking at something else at the time, or your eyes are closed, etc).
"Disabled" is OK (using words such as "people with disabilities" or "differently-abled" or "people living with disabilities" or whatever, does not help), but usually it is better to specify the specific disability (e.g. "blind" or "deaf"), which is usually much more helpful than writing "disabled". (Although, in some contexts, it may be sensible to write "disabled", because it isn't about a specific kind of disabilities. Even in some cases, "differently-abled" may be appropriate, possibly.)
Accessibility features can be helpful whether or not you are blind, deaf, or other kind of disabilities. For this reason, it is helpful to not restrict their usefulness or to claim that they are only good if you are disabled in this way. (For example, many people can use captions on TV even if you are not deaf, although they are also useful if you are deaf, which should not be disregarded.) I think that many kinds of features can be useful whether or not you are blind/deaf/etc, if the system is well-designed.
In some cases, there just aren't any good words to describe some unusual situations clearly, though.
