I had exactly the same issue. I am surprised how neither cloudflare nor google have been sued for making most of the web inaccessible to people with disabilities.
Shouldn't that liability be with the operators of websites that use those captchas if they're required to be blind-accessible? If they get sued, it'll apply pressure up the supply chain.
We must stop giving excuses to the massive centralization, to the enormous companies that step in and rent-seek what is supposed to be a distributed system.
The most powerful tool we could have to get a proper internet back is the simple concept of accountability. If I was a bakery and I made a cake with poison because I was specifically asked to do so by a customer, I would still be accountable for the dangerous thing I made.
Stop making excuses for these companies with basically infinite money. They are the last ones who need it. What we all need from them is accountability.

Hell, sue them both. Neither entity deserves a free pass. They both had a part to play in the exclusion.
