Thank you for the guidance @dang - rereading now. Feel free to ignore the rest of this discussion message @dang - unless there is some Cautioning I'm overlooking it on your part to me, here?
* "Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something." -- is what I'm noticing from the Guidelines. I dismissed @luckylion (hi!) as categorizing this subject as being off-topic for HN.
Reframing in the context of the Guidelines:
I learn from the topic an appreciation for Accessibility (the technology-area that enables marginalized groups). Specifically, how it can be possible for a severely handicapped designer to contribute, greatly in this case, only having the use of fingers for up to 2 hours.
And I learn, how bias by leadership poses difficulties countering it non-linearly / disproportionately to that marginalized individual. Specifically the disabled ex-employee contacted the CEO through Tweeting, the next-most-convenient technology route after failing to successfully use corporate facilities (https://twitter.com/anothercohen/status/1632931816750346242).
It is hard in my experience to contradict and correct the dominant paradigm when it's at fault. As a technologist, I think about the problems society faces, in this case posed by Twitter Inc's reliance on Tweeting, to a disabled individual.
So I did/do think this subject is appropriate for HN - it's something to be built on; I disagree with the subject's flagging since many of the spin-off discussions are what deserve flagging for "celebrity" character politics.
Certainly the key-takeaway, ADA / Civil Rights violation + character-maligning by innovator of another innovator, is dressed-up in "celebrity". Though not tragic; the now-fired disabled employee seems to be excelling at life.
