I will go out on a limb here as someone who has been diagnosed with 'unclassified impulse control issues' (I didn't really know how to keep my mouth shut and emotions in check), but is now just considered 'abnormal but we trust you to medicate yourself properly' which is a weird place to be in, while there may be an element of ableism in there, a large part of it comes from the fact that these people are on the very low end of the spectrum of their anxiety disorders and yet have found a way through self-medication to trigger and intensify it in themselves.

If they were higher on the spectrum with it, it likely would have triggered earlier, and they would be more self-conscious from having to deal with it when they were younger. This is, of course, assuming they had access to mental health care at all. The fact of the matter is that they are absolutely correct to be paranoid. We are being passively observed, usually illegally, and our data is then used to feed us content and products all the time, tapping into our greatest insecurities and FOMO to do so. Most anxiety-ridden people I know are anxiety-ridden because they have full understanding of this at all times and it absolutely paralyzes them, with the most common one I have personally witnessed being someone having a literal mental breakdown over choice and calorie anxiety from a fast food menu. Which they are correct to be anxious over because too much of that stuff is definitely bad for you. For myself, massive anxiety hits whenever I enter a big city, because it suddenly dawns on me that there are hundreds of thousands, of not millions of people living there, most of whom will never be aware of me nor I of them.

In this way, this kind of LLM induced anxiety is both stupid in its creation and ableist in not having sympathy despite the stupidity of it. TLDR: It can be both.
