"I hate how children will leave school, with a microsoft cloud account by default... which presumably will start asking for cash somewhere down the line, or face their childhood classroom experiences and work... wiped."
While I'm no fan of the commercialisation seen in schools, the Microsoft Cloud accounts they have at school are free for as long as they get to keep them (for many uni students, that's for life), and are essentially the same as a corporate account - they're on the school's domain, and use the education version of Microsoft's cloud platform, which is quite similar what is sold for enterprise. Their school account won't magically start requiring money to access. Some push may happen, on a school level, toward paid Microsoft services down the line, but it'd be a totally separate account.
