There is some pretty consequential conflation of the difference between "public" and "private" above. I don't have to make my house wheelchair accessible because it's my house. And I'm not violating anyone's human rights by foregoing the above (and neither are you).
Similarly, I'm confused by your example of an employer moving essential services to non-accessible software because your are not blaming Dreebly Chat for making non-accessible software, rather, the employer for choosing to move to a platform that discriminates against its employees. You seem to understand where the blame lies... and it doesn't support your premise.
My critique is certainly levied against legislation, not "other political action". In your haste to make a counter-argument you may have forgotten what you are arguing against.
