This article goes against what I’ve noticed in schools, as a teacher.

In schools I’ve worked in that block sites students want to reach (games or video streaming, almost exclusively), one kid in the school figures out how to sign up for a free VPN, and it spreads quickly until everyone in the school is using a crappy (likely unsafe) VPN. They don’t have the knowledge to seek out a reputable VPN; they just get whatever spyware they find first that works.

There’s no point filtering school Internet, except for known porn sites. Block PornHub, obviously, but as soon as you block YouTube or Cool Math Games, then every student in the school will be using a shitty VPN by the end of the month.

That said, students aren’t going to put the effort in to get around blocks for schoolwork. Obviously. They aren’t going to open the VPN for that!
