It's also a reminder that no mater how secure you think you are, some third party may have access.

Consider that TAO (or SSF) can probably get through your firewall and router, and maybe into the management engine on the servers with your critical data.

The only thing you've got going for you is that they will (probably) keep your data secure (for themselves).

I mean if I create an offline private key and encrypt my message to be only read with my public key and I’ve learned about math and encryption. I can be assured that my receiver would need to be compromised.

I don’t like these general observation comments. This kind of makes it unappealing to learn about encryption, but it’s worth it and makes you choose either a proper encrypted software or use a key for secret messages.
