I agree with you that generally people who complain about assistive devices do not consider any form of disability in their analysis. But the way that the consumer tech industry is shaped makes selling assistive devices really hard. Investors only want to invest in things that will be the next iPhone which makes actual assistive tech a really tough industry because the market is too small. So companies broaden try to broaden their reach but in order to do that they sacrifice the resilience, durability, reliability that those under-served communities really need. Most abled people can handle the 80% accuracy of a voice assistant, but for someone who needs an assistive device, that 20% failure rate can be brutal. The bar is so much higher to help those communities, and most companies wont bother.

Basically, if you want to make a medical assistive device, you kind of have to be all in on it, instead of trying to convince everyone that your device is the future of human-computer interaction (because its probably not and you'll just forget and ignore those communities)
