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

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

> Open schematics for a PCB don't make it any harder to hide a backdoor.

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

The backdoor would be in the firmware and open schematics for a PCB don't say anything about open firmware right....

You're not wrong. I only claim that there are fewer places to hide a backdoor when the schematics is open (just like with FLOSS software).
