Google Classroom
I think the public educational IT system should not be outsourced to the private sector, where schools completely lose control of the data and depend more or less on the good will of the company. University courses should not be organized by Facebook and pupils should not be forced to use IT systems of non-trustworthy companies like Google, which earn money by profiling their customers.
Maybe my view is too German, but I think of education as an sovereign function of the state, where everything (theoretically) can be controlled by the citizens (yes, I know that this is some kind of optimistic). We should teach kids to think critical about centralization of data and knowledge and show them how to manage their digital lives with free and open tools which respect the users rights.
