One of my floss friend noticed to me that phoronix reports "Atheros
Publishes Open-Source WiFi Firmware"
Source is https://github.com/qca/open-ath9k-htc-firmware and its license
seems to be DFSG-free one.
Now Debian provides it as firmware-atheros package (Source: firmware-nonfree)
so it may help users to run their laptops without annoying to install
