I was a bit surprised to not find a reference to the singularly most irritating thing about Google's recaptcha - that it treats me - the one trying to authenticate - as a free source of data labels for its ML systems. I guess I'm unlikely to be the only one irked by another "identify all the bicycles" challenge. Do the labels I provide belong to me or to Google? .. when I signed no job contract with them to provide that information. edit: aha! https://www.hcaptcha.com/labeling https://www.hcaptcha.com/labeling - that's why it wasn't mentioned. One more labelling service that I won't like.
