My boys have chromebooks, it’s almost mandatory for school now, and I get why teachers need the whole class to have a similar locally-networked tool. Problem is we as parents can't set anything, as we don't have 'developer' access, and the school controls their accounts. So at home, they do stupid stuff. The hardware is ok, I wish it was just linux. About what google gets - I doubt the current data is so valuable, they play a long game hoping to lock young people into their ecosystem, to profit from people with cash/energy in their 20s.
