I thought it was common knowledge that we've been providing free training for machnine learning since the around the first introduction of captcha. Not sure if the absolute first human verification systems were machine training, but it definitely became that quite quickly. Like, did everyone just forget about the "provide feedback" button on your search pages? Or when google maps used to ask if its information was accurate? And the fact that google/youtube/facebook/etc have almost always used your interactions to train algorithms to tune the machine learning not just for you but for everyone? Why should it be any surprise that every new offering from these companies tracks user data in order to improve the economic efficiency of their models just as every single prior offering from these companies has always done?
