When hCaptcha first came out I went on CloudFlare's site and ranted about how bad the accessibility was for screen readers. They seemed to have fixed it a bit since then, but I don't think they really test or put much effort in to it. Ultimately CAPTCHAs exclude anyone that is worse off than an AI. I hate it. You could try setting your browser agent to some Windows thing, that might help. Jookia.
