What are we to do in an era with out privacy?

On the topic of "suppressing free speech": That is so 20th century. Today's leaders have learned from their mistakes and are now using more sophisticated means of controlling the populace. Cancelling, "Othering", Shadow-banning ... those are much more effective. As a specific example, in Germany (where I was born and lived until 2021) during the pandemic the word "Querdenker" emerged. Pure genius! Instead of suppressing criticism of the government, it was branded as pure lunacy, and people were conditioned by basically all mainstream media to ridicule any criticism without even listening to the argument. This mechanism automatically contains/isolates any criticism of the system without the need for any authoritarian action someone could point the finger at and complain about. 

You are probably aware that the Querdenker movement introduced the term for themselves before anybody else used it to refer to them... Also their argument came to the people from all over the place, but many people just didn't like it. Tough luck. I don't know a single person who wasn't aware that it was around and where to find what the Querdenkers think. Actually pretty much all people I know got far more exposition to it than they wanted (except of course those who agreed with the argument, as everybody likes to have their opinions backed up by others). 

It's fascinating - from my childhood I remember (or at least I think I do) that people used to be really critical of the government, to the point that they had to resign when they messed up too badly. These days nobody ever resigns, or if they do they are just moved to different positions.
