Earlier quoted context omitted.
The audio CAPTCHA always works first try for me. The image CAPTCHA can go eff itself, it would always take me five tries while the images loaded super slowly.
Yes, the audio CAPTCHA is easier to solve, but the audio challenge is blocked [1] if you are not in a good network neighbourhood or they can't collect enough tracking data to classify your visit. [1] https://github.com/w3c/apa/issues/25
I kind of wonder if it would be possible to force the issue legally as an accessibility problem, but other people than me would need to do it, and in any case it feels a kind of dirty to me to use blind accessibility as a tool in the fight for privacy.
On the other hand, it also feels dirty to me that being blind would mean you're not allowed to do as much on the web to protect your privacy. Blind people should be able to use Tor.
