tbh you sound like an ungrateful stuff.
You realize your parents pay the internet fee, they can do whatever they loving please with their internet. Until you live on your own your parents control what goes on in your life, that's how it is. Sure you can disagree with what they believe but they simply have the right to do what they do.
Saying you want to move out is horse stuff, I lived with two roommates for about 4 1/2 months during the school year and I can tell you, it sucked. It was school in the morning, work right after until about 11pm, then sleeping for the next day. I worked Saturdays as well so my only free day was Sunday, and it usually consisted of sleeping all day.
Even working 40+ hours a week I barely ever had money to spend that wasn't going to my part of the rent, bills, or things I couldn't live without.
Appreciate the fact your parents still hold you as their financial burden and accept that they can do what they want with their internet, just enjoy it bro.
