I disagree. I think the article is about the motivations of people with social anxiety. I'd agree it makes assumptions and paints with a broad brush but it feels relevant to some of the socially anxious people I know.
I edited and rephrased a lot of my posts and the other replies and maybe my though process is clearer now. I didn't word it all too well, forgive me for not being a native, I struggled to bring my point across in an enunciated way.
Thank you for the improvements, I think it does read better now. Thank you for making the effort to converse in a second language.
I still think you are making a point that feels orthogonal to the article. The author presents (supported by public expressions of the opinion) that some people believe social anxiety is based on wanting to be liked. While to that point your study indicating that autistic people may be at a disadvantage on the getting people to like them front, the author is then rejecting that proposition (i.e. that the socially anxious are actually concerned about avoiding dislike). I suppose your point can be understood relevant there too, in that for the autistic population, the baseline "disliked" level is higher. However, the article remains about the internal focus of those with social anxiety (whether it over generalizes or not) between "liked" and "not disliked" which seems orthogonal to any baseline "likability" considerations for one or any other sub-population.
[edit: s/"liked" level is lower/"disliked" level is higher/ for higher congruence with context]
