This kind of crap is fundamentally a violation of students' right to privacy. They deserve to grow up in a safe environment away from the prying eyes of crappy adults.
I mean, to that point, how secure is GoGuardian? Who has access to the administrative tools/etc.? What APTs have gained access to its systems? A system breach of any online system is effectively inevitable, or at least impossible to rule out. Do you think everyone with a Verkada camera thought hackers around the world are going to be tuning into their video feed?[0]
Anyway, stop buying tech that force you to give up your right to privacy to use it. You don't have to go 100%, but at least start looking at these kind of things before you shell out your hard-earned dollars.
