Sorry, wasn't intending to be vague but I also don't like directly accusing anyone of anything and would rather people trying to find the info on their own. Guess I was wrong to want that!
It was discussed in a thread here on GAF:

and if you google Cronus Conspiracy there's an article on another site about it. Other information is around about it and can apparently be backed up, so I'd, personally, rather not provide money to a company that has actively engaged in this nonsense.
The other part being that I prefer the Brook for not requiring extra hardware and wonky setups to work. The fact they sell adapters for each situation is not a cheap one, but I bet it's because of how they make the devices not require constant re-authentication. That and, to be honest, I only really needed to use an Elite on my PS4.
