Research Findings:

reCAPTCHA v2 is not effective in preventing bots and fraud, despite its intended purpose
reCAPTCHA v2 can be defeated by bots 70-100% of the time
reCAPTCHA v3, the latest version, is also vulnerable to attacks and has been beaten 97% of the time
reCAPTCHA interactions impose a significant cost on users, with an estimated 819 million hours of human time spent on reCAPTCHA over 13 years, which corresponds to at least $6.1 billion USD in wages
Google has potentially profited $888 billion from cookies [created by reCAPTCHA sessions] and $8.75–32.3 billion per each sale of their total labeled data set
Google should bear the cost of detecting bots, rather than shifting it to users

"The conclusion can be extended that the true purpose of reCAPTCHA v2 is a free image-labeling labor and tracking cookie farm for advertising and data profit masquerading as a security service," the paper declares.

In a statement provided to The Register after this story was filed, a Google spokesperson said: "reCAPTCHA user data is not used for any other purpose than to improve the reCAPTCHA service, which the terms of service make clear. Further, a majority of our user base have moved to reCAPTCHA v3, which improves fraud detection with invisible scoring. Even if a site were still on the previous generation of the product, reCAPTCHA v2 visual challenge images are all pre-labeled and user input plays no role in image labeling."

I always thought they are just getting the training data for AI using these.

It is undoubtedly a new piece of research, but the cause is always the same: corporations exploit people because they are taken out of government and democratic control effectively everywhere.

Some corporations employ more people and have bigger budgets than some countries and they often influence people's lives more than the government. Yet they're effectively electoral monarchies where electors and monarchs are just a bunch of rich assholes who respond to nobody.

Only when we change that system then those headlines will stop.

I mean, duh? With proof of work captchas existing, there's no reason to have those image selection captchas... Ever...

How those work is by having the server generate a puzzle. Server side this is cheap to generate, while client side solving is "hard". The server can even choose the difficulty of the puzzle, and even set it dynamically. This means that when your website is under light load the captcha can be really easy/fast to solve. If your website is under attack however the captcha can be set to take seconds to solve.
