It's either GPL (like touchscreen config) or something else
redistributeable.

Yes, but I don't know yet for sure whether it's really needed for all
firmware files.

For example, the T30 Broadcom WiFi doesn't work using stock
linux-firmware, it's on my to-do list to try to figure out why.

While Bluetooth FW seems to be reusable be many different devices,
although (AFAIK) nobody cared to upstream it to the linux-firmware.
