The worst thing about your post (that isn't at all your fault), is that there isn't a strong argument for them palatable to the hegemony short of "ableism."
If the explanation in your first paragraph is true, then does it stand to reason that there are non-autistic people with weak soft skills? Or simply prefer an individualistic, distraction-free workplace?
My answer to this rhetorical question is: Yes, obviously, as long as you don't tautologically define anyone with a below-threshold appetite for social interaction at work as autistic.
It's fashionable in SV to talk of empathy, tolerance, acceptance etc... Yet from the outside I see a very close-minded bubble that demands people comport to so many social standards that nobody actually finds necessary for professionals to work productively. They'll let people get away with non-conformance only if they've got an excuse that would be a political landmine to cross (e.g. ableism re: autism).
