I do not get what you are trying to say. The fact the device has a logo does not imply anything: they already paid the licence fee to stick this logo on them. As with the frequency used: that is the device maker's responsibility: neither the user, nor the stack developer can be liable for it (device should have obtained an FCC agreement or similar).
Moreover as for the Bluetooth fees according to Bluetooth SIG website (
here) you should be member to develop anything based upon their specifications, but from the above mentioned webpage one can read that "Adopter membership" is free. Qualification process and listing product are not free (~$8.000 USD) however I was not able to determine if those are *required*.
