how can i live peacfully knowing that i can be suspected of anything just because i made a joke here or said something there?
You’ve never been able to say things publicly (or, since the internet, publish something that the entire world can read) and expect to be shielded from the consequences. There is always a risk that comes with speaking freely, especially if powerful people perceive your words as a challenge to their power.
The erosion of privacy protections is a reason to despair, but it is also a reason to speak more.
You asked how can you live peacefully knowing that your words might be used against you. I don’t believe you can, and I also don’t believe you ever truly could. But I also don’t believe that is a reason to self-censor.
