I saw a post on the GrapheneOS forum of someone who was accosted by Google with this requirement, so they are certainly using it.

It's interesting the parallels of Google's recaptcha and Cloudflare turnstile.

Cloudflare is free, no image selector, allows VPNs and Tor for the most part, just 0 click with a good ip reputation and 1 click with a bad one.

Recaptcha is paid, trains waymos, sucks millions of hours of human time, asks for camera access, asks for a phone attestation, blocks VPNs/Tor.

Thank god less sites are using ReCAPTCHA.

Looking forward to some other solutions gaining prominence eventually as well.

Like that Anime girl one.
