Of course if even educational use of laptops is restricted then personal mobile devices would also be. They are already banned in my country.
If the article was “instead of a national ban, we should look at school-wide ban”, I would be sympathetic.
FWIW, American states are doing exactly this[1], people still complain

My reading of the article is that it criticizes the implementation of this policy and the methodology behind it, which I agree with.
Living in a country that moved quickly from a "social media ban" to an "adult content ban" in the space of 3 months, I feel that these policies are overreach due to how they must be implemented. As in, they require all users to provide verification, not just the targeted cohort.
