As an autistic who has been online since the early 90s, this article didn't speak to me at all. My autistic internet comprised IRC and USENET, and it died when LiveJournal died. I still have close friends from those days, when I have no close friends "IRL"- I can't say that for anyone I met on Twitter or Facebook, in fact I found both of those platforms to begin enshittifying looong before any of the NTs began to notice it.
I don't think it's just because I'm an older AuDHD woman, I think the existence of Facebook and Twitter from the mid to late 00s killed the autistic internet.
I agree with the "don't use your autism as an excuse" side, but as a middle-aged AuDHD woman who can no longer hold any kind of paid work due to burnout caused by years of faking it in a high pressure career that I loved dearly and would have done for life if burnout hadn't disabled me- I'm really repulsed the idea that all of us should just try harder to fit in. I did that, and it eventually destroyed me. It is not something that I'd advocate anyone else doing.
