What about just applying that reason only when people want something from you.
Most people don't want anything from you. Some people like just chatting. Salesmen will feel smothering and uncomfortable because they want something from you. Advertisements trigger me because it's so obvious (in my mind) they want something from you. News feels this way too.
How can I tell? The same cues that fool people who focus on the surface-level: flashiness, bravado, loudness, taking the subject matter to things I do not care about. Trying to make me feel emotions (fomo, FUD, even excitement).
You could use it as dating advice: people are turned off when you want something from them too much.
Not all that glitters is gold.
Except a smart scammer won't do it as a hard sell and look like they need you. They know as well as anyone that aggressive sales look suspicious. Madoff waited for people to come to him.
What about cutting off just mobile data + school wifi? Everybody with wifi or a network connection elsewhere would be just fine. Still extreme, but dramatically less disruptive.
Plausibly you could limit this further, to block data only on phone masts near schools.
Still an ridiculous measure, but I'm really surprised that they've taken the most extreme measure possible instead of trying to limit the fallout at least a little bit. It's not like nobody is using it - https://data.worldbank.org/indicator/IT.NET.USER.ZS?location... shows that by 2017 more than 1/3 of Syrians had internet access, and rapidly increasing.
