What you can and can't say is already monitored by the government. You know this already when you hesitate before posting your honest opinion online, because you know they'll come for you. You know they'll blackmail you or smear your character if you ever go public, or straight up kill you. It's happening now and it's already happened. 4chan and Reddit are already in the hands of government minders. "Don't stir the pot, don't have an unpopular opinion, or we'll fucking kill you." The dystopian future is upon us right fucking now. IT NEVER USED TO BE LIKE THIS. DON'T LET THIS BECOME THE NEW NORMAL. DON'T LET THEM CONTROL WHAT YOU CAN AND CAN'T SAY AND WHAT YOU THINK OR HOW YOU CHOOSE TO BEHAVE. IT'S HERE, NOW.
If you're not using a VPN to post online, research one now, and grab TOR while you're at it. Remember to change your DNS servers too. Take control of your voice and let your opinion be heard. Don't live in fear.
