Some US schools plan to track the movements of students within the school, for contact tracing. This is on top of demanding they be used by proprietary malware (it spies on them) to do their work, and giving their personal data to companies that profile them.

Contact tracing is legitimate if it collects no data about contacts between people when neither of them is spreading the virus. But if the system is tied to a snoop-phone, it is sure to be an additional injustice.
