100% with you, I don't understand that people feel they have privacy in their house but not on the internet. Those people just don't understand how humans work and how we get better as a species.
I will forever keep trying to communicate without anyone else being able to read it. You can't ban my ability to use math to encrypt things. Still, the thought police keeps popping up. They can drag me to jail. I am a good person, a father, but my thoughts are my own. (just kidding, I'll give up all my s* when they actually drag me away from my family, but maybe I'll let them drag me for some meters for the show, to make a point, and hope people are filming it.)
There are things like Ham radio and meshtastic (uses lora). It's all slow of course (atm).
