I trust smartphones with open schematics. Not because it's impossible to hide a backdoor but because it's harder.

Open schematics for a PCB don't make it any harder to hide a backdoor. You're talking about devices which still have an entirely closed source SoC with all of the real complexity. The products you're repeatedly marketing here use a bunch of low end components with very poor security including lacking ongoing patches for vulnerabilities and basic standard security protections. They're falsely marketed as open but are actually closed source hardware with closed source firmware. A closed source SoC, Wi-Fi, Bluetooth, cellular, NFC, SSD, touchscreen, camera, etc. attached to a PCB with open schematics is not open hardware.

  • > They're falsely marketed as open but are actually closed source hardware

    This is just a strawman: Nobody claimed they were open hardware.

    This is like saying that FLOSS doesn't make it harder to hide a backdoor. Of course it does.

Exactly.

  • They're talking about devices known to be extraordinarily insecure, which are still closed source hardware with closed source firmware. Having schematics for the board does not avoid trusting the hardware. It's still a closed source SoC and the same for the other components such as the SSD, Wi-Fi, Bluetooth, cellular, etc. but those components are much less secure without proper updates and security protections. The whole point of an SoC is that it has the complexity of a traditional CPU, GPU, motherboard and other components merged into a single chip, and that's entirely closed source with closed source firmware on those devices.

    • > extraordinarily insecure

      So you are just attacking another FLOSS community with false [0] claims. This is suspicious.

      [0] You can't say "extraordinary insecure" without specifying a threat model. For some threat models, GrapheneOS is less secure, e.g., https://news.ycombinator.com/item?id=45556788

      Also, if I explicitly don't trust Google with anything, GOS is extraordinarily insecure for me until a new vendor appears.
