To the extent that it matters, I think the missing link here is "primary education should support a parent's intent to limit unrestricted internet access for their children." That is, during school activities where internet use is unavoidable, require supervision.
Don't get me started. We try to restrict internet time, no Youtube (Shorts are poison/heroin), TikTok, etc. They go to primary school and there is a teacher that makes TikTok videos at school, they can play Roblox in breaks, etc. (Aside from this issue, the teachers are great though!)
There are only so many battles you can choose as a parent (not getting your kids photographed, put on Facebook, etc.).
In contrast to what the grandparent states, the government should unambiguously state: no smartphones, social media, and online games in primary school, period. That's the only way to make it work. Ironically, smartphones are forbidden in all high schools here.
