librem5 is a binary blob provider. and you mostly fell for a scam.
they signed the same NDA as other OEM.
your so called open source drivers are full of binary blobs, which ironically are just the chip manufacturer reference implementation code compiled, with little else.
librem5 just shouts the lie louder. it's as closed source as any other device. like raspberrypi in terms of drivers.
...and I'm not going into the illegal investment scam librem company spams every one of their customers.
