The other problem with this is that there are few CAPTCHA alternatives.

CF turnstile is one, but of course that means Cloudflare owns even more of the web.

HCaptcha is inaccessible and actively discriminatory against individuals with disabilities and refuses to change, to the point that I suspect the only way that they will do anything is to file a class-action against them and sue them into the ground.

And I... Can't think of anything else. Other than to just get rid of Captchas entirely.
