I'm not worried about the keyboard I purchased or my hardware vendor. Well I am, but far less so than the prospect of a foreign USB device being plugged in and managing to execute malicious code. Think someone quickly inserting a device as they walk by, secretly swapping out one of my peripherals while I'm not around, or similar. Authorization on first use is more than sufficient to mitigate this type of attack, and if you add end-to-end encryption you can also prevent USB keyloggers.
