I am Portuguese, have family ties with teachers still into the active, I guess.
That kind of stuff is mostly US school system, schools in countries that go with USA into G7 meetings, or wealthy enough for that kind of stuff maybe.
Not every country has the pleasure to enjoy a school system swimming in money to offer computers to kids, in every single school.
Not even during COVID was every Portuguese family granted the pleasure to have a device offered to them, some lucky ones did, a large majority only saw them on the news, and as usual the burden was on the family to come up with a solution to all their kids attending the various school levels.
And lets not even go to such great stuff like Magalhães, e-escola, and who got to profit from it.
I'm writing from personal experience in a middle of the table public school, with a single IT guy helping out around 1000 pupils, who regularly get their computers locked with said MDM.
It's possible other school districts with a less diligent, but similarly overworked, IT guy just give up and don't even hand out the computers anymore, especially if they don't have enough of them, after being on their second or third kid.
