We are going to provide a solution, which removes Cinavia from the audio. It will suck. (As all similar 3rd party "solutions" do - current or future).
The best way to deal with Cinavia is and will be to use a player, which won't trigger it. This would a a PC player, or a player which is not able to play original Blu-ray discs. (Any of the many "media players" starting at 40 bucks, if you count in the raspberry pi).
For DVDs I suggest to use a DVD player, which won't care about Cinavia.
I totally agree with what you are saying but I think the reason why people are asking about Slysoft etc removing the Watermark is because of comments made by Peer.
This of course was also before Slysoft had disabled Player detection.

It is Post #563 in the Doom9 Forum headed: "Cinavia"/Verance BluRay audio watermark protection.
It is in response to Ghitulescu.

So, you're somehow, based on a gut feeling (?), insisting on the impossibility of removing that watermark without destroying or "staining" the actual content.
I don't know how much thought you have really spent on that matter or how qualified you are to give an expertise.
Just this much: it is very plausible, that you can apply a mechanism, that renders the watermark useless, at least without percievably further worstening the quality of the signal.
It is even likely that - depending on the level of sophistication - removal would re-improve the quality, more closely resembling the original.
A watermark consists of either subtraction or modification of existing information or of addition or a combination thereof in a specific way.
Anyone can imagine, that - once you know how a watermark has been applied, you can, to a certain level, work yourself backward again.
It's not quite as simple as reversing
f(x) -> f'(x)
as the watermarking is not neccessarily or even likely a bijective projection and also in many situations certain parts of the original signal already coincidentally resembled parts of the watermark, but if you apply some additional signal processing for statistical prediction, you will very likely be ending up repairing more of the original signal than you will be messing it up.
I'd also like to point out: it has been done before with another audio watermarking scheme. The results were excellent.
The only difference in case of Cinavia is that it may be more difficult to make the removal remain effective for all detection devices.
