"Use nothing commercial ever" is probably too extreme. I'd agree with the parent that schools shouldn't be getting kids to use things like GSuite, but not solely because it's commercial - the problem is the data management practices of these companies, which the state should not be supporting by forcing children to use these services to complete their education and inevitably giving companies like Google huge amounts of personal data. This isn't a problem with textbooks, commercial or otherwise.
