I think the main thrust is that the tool is not fit for purpose, but Google benefits from it anyways. They get the AI training data, but the website owners still get hammered by bots, and privacy conscious users and users who have the audacity to be from a country flagged by RECAPTCHA get to struggle. Living in Russia at the moment, I almost prefer the sites that just outright block me to the stupid RECAPTCHA that cycles me through 3-4 iterations of images only to ask me to try again. RECAPTCHA is no longer doing what it promised, and that's the general thrust of the article; the bots are just getting too good for it.
