Ableism in the Free Software Movement Typically Comes From GAFAM Operatives and Proprietary Software Apologists
And their hired guns
In my personal experience, which I've written a great deal about over the years, the worst hostility or hostilities towards people with disabilities do not come from Computer Scientists or Free software activists, they come from trolls on GAFAM's payroll. This hostility (or hostilities) is ever more clear when it comes to smears thrown Richard Stallman's way, typically a sort of low-grade "concern trolling". In my experience, a lot of this boils down to projection tactics as hugely flawed people (psychopathic, psychotic and narcissistic people) keep picking on an old man because he doesn't move his pupils and hands the way they "expect" him to, hence he is "weird" or "creepy" or "spooky".
If you notice people like these in your community, be wary; they might be toxic, power-hungry liabilities who are worth shunning.
In recent years we've witnessed similar tactics being used against Daniel Pocock (repeatedly in fact; he clearly has very strong social skills) and then, accompanied by death threats, they did the same to me, calling me "autistic" while threatening to "shut down" my "existence". █

Ironically this image was sent to Daniel Pocock by a sockpuppet/burner account of a Canadian who describes himself as autistic. At the same time this Canadian was talking to the man who tried to put my wife in prison after he had tricked California into doing the same to his own spouse.
