So if the L5 switches are actually software switches that just send some low-level signal to the OS or some firmware somewhere, I’m curious what that means for the cellular service radio chip. My understanding is that chip has it’s own proprietary stuff running on it, and Purism insisted on a separate chip so that the proprietary stuff would be more isolated or something.
So if the “hardware” switch is sending a signal to the Libre Software, saying please stop using the cell radio, how does that actually effect the separate proprietary chip? Is power actually cut to that chip? Or does the separated proprietary chip continue to run, only it is ignored by the Libre OS? If that’s the case, then the cellular “hardware” switch seems to not do anything for privacy, as the proprietary cell radio can continue to happily chirp to its towers, revealing your location and device status to anyone who is interested (Google).
Clarification on the design is appreciated!
