They're not free. They're certainly not "free" as in they respect my freedoms, nor the freedoms of any child or parent that has to dirty themselves with it. It might not be a cabal with the schools, but surveillance capitalists are certainly a cabal unto themselves; a nasty and greedy cabal which has no place near public institutions.
As schools attach themselves to these incredibly abusive products, I sincerely hope the publics' opinion of schools drops with exponential relation.
