Because it's true, and I know what he said, I am not confused at all. Did you not read anything at all?

On the Librem laptop, the tampering is done by PureBoot and inject into /run/firmware. The other user was linking the stuff with the laptop.

*On a Librem 5, it is stored on a separate chip, then they read it with the initramfs, then mount it on top of the regular filesystem at /lib/firmware*.

Like I said, it's just shuffling stuff around.

Here is the actual code, if you care enough to read it: https://source.puri.sm/Librem5/librem5-fw-jail/-/blob/pureos...

If you can't read code, here is the marketing material: https://puri.sm/posts/shipping-new-sparklan-wifi-cards-with-...

If you don't know that the firmware for components/peripherals can either be uploaded to them by Linux or just stored on some flash chip on the component, read: https://www.chromium.org/chromium-os/developer-library/refer...
