I'm sorry you're in a bad situation, but the reality is that technologies grant power, and some nations don't want their citizens empowered, while other nations don't want their power through technology used by enemy nations against them. In order to have some rule that governments can't do that, you would require a higher, metagovernment, which would then have the same sort of power and require the same oversight, requiring and even higher metagovernment, and so on. Hence why government is always a scam...it promises safety and justice the way the mob does, through violence and threats.
