Guess who now has a comically oversized USB Bluetooth dongle with massive antenna that provides wireless headphone coverage through the whole house?
(It's technically a WiFi 6 dongle with Bluetooth 5.3 support on the side (or rather "Wireless 5.3" support, in the manufacturer's words), but there's no Linux drivers for the WiFi part, only for the Bluetooth part...)
Slight correction: Linux drivers *do* exist, but not in the kernel; there's some random person's repository that contains out-of-tree drivers which, according to them, "are not official and are hacked together from other Realtek drivers"
