Systemic discrimination, happens all the time. I am blind. I regularily fail the "tell computers and humans apart" test. You imagine, that feels very much like the dehumanisation it is. Big tech couldn't care less. After all, they need to protect themselves against spammers. Much like the guy who was on the HN frontpage just a few days ago, arguing that he is now trashing accessibility because he doesn't want to be web scraped. If you raise these issues with devs, all you get it pushback, no understanding at all. Thats the way it is. If you are amongst a minority small enough and without a rainbow coloured flag, you end up being ignored, stepped over, and pushed aside. If you are lucky. If you are unlucky, and you raise your voice, you will be critizied for pointing out the obvious.
I agree anti-bot vigilantes as well as corporate anti-ddos middle-wares have had a detrimental impact on accessibility. I'm afraid they consider your use case as acceptable collateral damage if they consider it at all.

Interesting, because he failed me too just because I use Firefox. Have you been told about the article or it actually worked with your screen reader software?
