At some point after the disbanding of the standards body manufactures went rogue and started creating and modifying protocols so theirs would/could be "fancier" than the competition. Now we get stuck with devices that may or may not be 100% functional across the board. Or we end up with my brand new stereo headphones only playing mono because some mgr's devices did follow the stereo protocol.
You discover any of that in your research?
Bluetooth is in the unlicensed ISM band, so there is no governing body involved, other than if you produce a product that emits outside the band or at too high a field strength (where the FCC will nail you), there is no 'authority'.
The Bluetooth Special Interest Group does settle on what the industry agrees to - but you can't stop any manufacturer from doing what they want to do.
