This isn't a defense, just an explanation... but it is also an explanation of why the entire idea of "we'll not give blind people a way past the CAPTCHA but just give a pass to 'real' blind people so we can pass ADA", which is that it should have been transparently obvious that this approach is completely infeasible and unscalable. As big as Google, Facebook, or Amazon are, they would struggle under the load of trying to create a system for determining who is "truly" blind... and that's still true if we ignore questions like exactly what "blind" is anyhow.
This shouldn't have gotten deployed and then become a problem; it should have been a 5 minute diversion in the meeting where it was proposed to analyze it's completely infeasible and never made it to so much as the design phase, let alone the deployment phase.
If you had a system for completely accurately identifying characteristics like "who is blind" in the presence of extremely hostile attacks on the system, you'd have something far more valuable than the CAPTCHA system itself! The whole idea intrinsically depends on having a stronger solution to the problems CAPTCHAs are meant to solve than the CAPTCHA system itself provides... it's fundamentally a logically unsound idea.
You are unfortunately describing worldcoin.
In terms of CAPTCHAs being valuable – the other day I couldn’t for the life of me solve a captcha. It was one of those “Solve the implicit question in the picture” kind where it can be hard to tell what it’s even asking you to do.
So I took a screenshot and put it in chatgpt. Got it right immediately.
The real detection mechanism is that you’re moving your mouse, thinking, and generally being slower than a bot anyway. The captcha itself is just a pointless annoyance.
User POV :"Wow, provider is a really shitty entity and had no respect for my legitimate problem."
Provider POV: "We get a huge number of illegitimate claims identical to legitimate ones regularly, the system would collapse if we didn't do heavy triage, the problem is the level of abuse, not a moral bankruptcy on our part."
I suppose "this is why we can't have nice things" captures some of it.
In several countries, the government issues certificates of blindness [1] which grant access to certain extra types of support. We don't want severely vision-impaired people being forced to drive, after all!
So there are legal standards for what exactly blind is, and certificates.
The question is whether tech companies are inclined to hire enough people to wrangle the paperwork involved in checking such certificates, worldwide.

In the USA, people are not yet required to provide identification when signing up for "free" services. There are real concerns around privacy.
A certification of blindness is exactly one of those privacy concerns, being a medical issue. You think it would be a good idea to give that private information to the criminal organizations of big tech?
This kind of article is actually useful because it raises the risk of actual reputational damage thus encouraging companies to do more.
It is not solved.
That is at most the beginning of a solution to the problem.
And in practice, it is little more than the beginning of the problem, as the government's definition of blindness is very unlikely to be a precise match to "has problems completing our visual CAPTCHA", and if multiple governments have standards there is no chance they will match.
Do not underestimate the resilience and resourcefulness of scammers. They aren't just some individuals here and there who decide one day that they could make a couple extra bucks spamming people, and just sort of start sending out whatever scam strikes their fancy. They're international businesses with engineering teams, and a constant feed of low-level operatives who can scam governments about how blind they are if the governments leave any hole in their system. They're thousands of people dedicating their full human-level intelligence to the task of defeating your system and extracting the value from it. They are not as easy to defeat as "let's just put the obvious certification in place", for the same reason that the CAPTCHA problem isn't solved with "Let's just issue everyone official identities".
I don't know about your country, but in my country the government is pretty keen on avoiding abuses of the benefits system. After all, a blind person gets tax breaks and cash benefits totalling about $5000/year.
So the existing system is used to dealing with financially motivated adversaries. I doubt the additional financial motivation of being able to bypass hCaptcha would mean much, in comparison.
That's what happens when trust erodes, and why we can't have nice things.
If anyone should be be more understanding and absorb the costs to appease the other, it's probably the big corp, not the little guy.
Audio captchas are inherently discriminatory to those with hearing issues or those that don't speak the 5 supported languages. They're also somewhat easy to solve with ASR models now. Text captchas are incredibly easy to solve with LLMs.
The only other alternative I see is some incredible tracking / surveillance machine (think an actual non-browser app that you have to run on your computer), but is that really what we want?
It's not unimaginable that just 0.001% of your users (in terms of actual humans / entities physically using your service) are fraudsters, but 99% of your signup or login attempts / interactions with your service / "I'm not a fraudster, pinky swear" support claims are fraudulent.
Every now and then turnstile does get a little borked but I can honestly say that I would rather just do without whatever I was trying to do than click 7 motorcycles. Hcaptcha and recaptcha are becoming my personal brown M&M indicator for additional bad user experiences in a given web property.
Perhaps not in all cases, but it can be. This article is literally about special treatment for accessibility purposes.
It's of course debatable if this is how things should be, but that's another discussion.
