Not sure if joking/trolling, but school computers don't generally ALLOW social media or chat apps like Discord and such, as well as harshly limit internet usage with guardrails. They're pretty locked down and even when at home monitor network usage.
I don't like laptops and such in schools, but kids ARE going to need to know how to use them to be successful and that's something a lot of parents can't teach.
When I was growing up, we had to learn how to type, how to use the Dewey Decimal System and library terminals to look up where books were for research and such. Later, we had Computer Labs to do this work and write reports and such... This is no different. Don't confuse a smartphone internet experience and its constant advertising and social aspects with what kids get on these laptops.
