Mmh, I think that forcing binary blobs out of the linux kernel is only useful if vendors move more work into the driver and silicon instead of firmware that cannot be updated, since each flash device is a security risk. But it could also backfire. The thunderbolt firmware for example is only update

I was surprised that linux-libre works on the dell xps 13. I'm considering buying an atheros wifi card, since that's the only thing that does not work. Does anyone know how to find out if there is a BIOS whitelist/blacklist? So it's just ARM boards that don't work with linux-libre?
