In my Clevo Laptop with @novacustom@mastodon.online and @3mdeb@fosstodon.org Coreboot firmware I now have replaced another proprietary part!
The Intel AX200 previously installed waits for a new use case, while I swapped in the Qualcomm Atheros Y8512 pci-e Wifi card, which has #blobfree drivers and thus runs fully on Linux, not just on some #nonfree kernels (that basically break the open source philosophy by including proprietary code in the single most critical root binary on your system)
It works great, just downloaded a Firefox release. zip over wifi without a single stutter!
I'm pretty sure this still has proprietary firmware baked into it
