In contrast to just buying ready made boards like for servers, the Librem5 is designed exclusively for us, we get to know every part, we get the schematics, gerbers and all manufacturing data, we carefully verify and analyze all of this and all production steps. Thus it is close to impossible to sneak in additional parts into the device. (“Close to impossible” means, if someone with really a lot of criminal energy bribing the manufacturer and introducing some malicious devices into our production, this will be hard to find - but anything else we would find and never ever ship - we will see and verify every stage of the production).
