Yeah, anything that’s not connected to the internet is generally safe.

lol there is some truth to that :)

At this point, I really think that the only way to have real privacy is to not use a computing device. It’s back to pen and paper and in person meetings.

The thing to remember is that cryptography is very tricky business, and even when an algorithm is sound on paper that does not guarantee that it’s implemented in a secure way. A famous example is when NSA “helped” develop the Diffie-Hellman cryptographic key exchange standard and introduced a vulnerability that nobody noticed for a very long time.

Any standard that’s been developed in conjunction with US agencies should be considered compromised in my opinion.

I use uBlock Origin and Privacy Badger.
