An important, if unfortunate, lesson to learn: you are being spied on, by people who demand your trust and give you none in return

Back when I was in school the web filtering got so draconian those of us in the know started keeping Tor browser on a thumb drive, and carrying it to whatever computer we were using. Some went as far as to reboot from a Linux image on said thumb drive. That was nearly 20 years ago, can't imagine it's any better now
