Know people that the government watches. Trust your messaging system blindly. Assume that low activity means no one is watching.
Every time I use signal, a messaging platform where I hold the keys, I find quotes of my messages in the wild. I challenge the person I sent them message to, and they will either never get it, intercepted, or usually never opened.
Do I blame signal? No. But the more blind trust you put into a popular tool, the more likely you have an unwanted recipient.
Just remember, the months and years it took to decrypt keys in the past, quantum computing can do in seconds and minutes. it just depends on how much the hacker is willing to invest into you.
