I've seen and read some of these stories as well but in my view they should come with a disclaimer that states that these cases involve a very small subset of patients with very severe symptoms who have not been able to improve, possibly because they have not yet found the correct treatment.
I do not want to downplay the severity of hyperacusis in any way, as I know from experience that it can be horrible and that no-one will truly understand what it's like if you don't experience it yourself, but what these stories do is that they play into the fear and anxiety of people who just go the condition, which leads to avoidance behavior which is counterproductive in treating it.
It's not uncommon to hear that people even commit suicide after very recently acquiring T and/or H, as they are convinced that they will never improve or habituate, while the reality could have been very different for them with time and treatment. I have no doubt that all the horror stories only contribute to their fears, and might even push them over the edge.
Recently I came across a similar article in my native language which basically stated that your life is over if you get T&H, so I e-mailed them politely asking them if they could at least include a small footnote that there are also people with T and/or H who either improve or habituate, and who go on to live a full life, but they refused as their articles need to be as 'exiting' as possible....
