I mean, people say use end to end encryption, VPN, Tor, Open Source Operating System, but I think one thing missed is the hardware is not really open source, and theres no practical open source alternative for hardware. There’s Intel ME, AMD PSP, so there’s probably one in phones. How can people be so confident these encryption is gonna stop intelligence agencies?
Yeah, we don’t. It’s generally hard/impossible to prove the nonexistence of something. Similar as with God. It’s unlikely, but we can’t prove he doesn’t exist with certainty. These proofs only work for very simple and contained systems.
