While I am
strongly opposed to any computer-based tool used by schools sending data about kids to the "big data companies" (if you want to call them that), I will point out that many school districts are using
Google Classroom as a platform. So hopefully the study did account for "legit" data sent to Google in this regard versus just raising hell that a Google IP address was a target at some point.
That being said, I have never read the license of GC but hope it was in the spirit of the "don't be evil" side of things, especially since I believe districts do pay for the service.
Now as far as Facebook getting data from these education sites? That is stepping over the line, bud..
To be honest, the schools were a little haphazard buying into the online services once COVID hit and frankly kids in K-12 need less screen time, not more. If your kid's school is leveraging online services as supplemental learning, question the principal about it - many of these sites are poorly written, poorly secured, and frankly make promises by people with hardly any education experience whereas your school's teacher who has a degree in education and spends all day with the kids and thinking about how best to teach them definitely knows a lot better than the staff behind i-teech-your-kids-gud.com.
