I truly want to understand more how that quote is despicable. As someone directly responsible for an individual with autism, I very much acknowledge that autistic people exist at several different levels of capabilities.
There is a vocal minority, of which your source is a part of, who are trying to "normalize" Autism. In order for it to be "natural neuro-divergence" or "a super power" you have to intentionally omit the negative aspects of the medium-functioning, and completely deny the existence of the low-functioning.
Using woke language to try and assuage the insecurities of high functioning autistic people might make people feel like big strong social justice warriors, but I will die on the hill that they are actually doing grave harm to many disabled people. To use the parlance, they are being problematic. And they should be ashamed of themselves for it.
Since we can agree on that I think we should all work together to change the definitions.
I get that it can be demoralizing, but I'd suggest it serves your cause better to be able to point to high-functioning cases as success stories to mitigate the stigma, lest the rest of the spectrum be dismissed as retarded beyond redemption (hence, eugenics).
