@alina@girldick.gay My family was similar. I don't think they really had the technical knowhow to restrict my Internet usage the way yours did, but they would often limit me by taking my devices away from me. This continued all the way up until I moved out to college.
I got so good at finding old devices to use to reach out to my friends and I'm fairly certain they never knew about most of it. Restricting access to "protect someone" is just a spark for creativity.
in addition, they forced me to use Life360, even when I was in college because I was still financially dependent on them. I had to go through so many damn hoops to go see my girlfriend who lived three hours away. And guess what? They still don't know about that. All that work and the only thing that comes out of it is I'm sneakier and Life360 probably illegally sold my location data to data brokers.
