I learned enough about security years ago that there's basically zero chance you're secure and almost 100% chance someone is watch everything you do online.
Whether they care is entirely separate.
Be careful when telling other campers that you think it's pointless to try to outrun a grizzly bear.
They may outwardly appear to agree with your statement, but it may be for very different reasons than you think.
Edit: clarification
I forget where I saw it but there’s an old adage along the lines of “even if your computer is unplugged, in a vault, with armed guards, it’s probably not safe”.
Could be accurate but governments can be profoundly incompetent even with great capability at their disposal
"Watching" is doing heavy lifting. "Able to watch" or "being recorded, along with terabytes of parallel information from others", is more apt. Actually discriminating the signal (communications from a desired target, or about a desired topic) from noise is the problem with your "nothing you do will stop them" theory.
Ah, yes, the "fuck it" approach to infosec.
