Edtech companies are already developing great power over the students in the schools where they operate, and it will get worse. They use their surveillance power to manipulate students , and to direct students into tracks towards various levels of knowledge, power and prestige.

They also structure their relationships so that they are never held responsible for the consequences.

The article argues that these companies should need to have licenses to operate. I am not against that, but I would go further. I say that the data acquired in a school about any student must not leave the school's control: whatever computers it gets onto must belong to the school and run free software. That way the school district and/or parents can control what it does with those data.
