I wouldn't get too excited yet, this is short on details. Just because the accusation was made does not mean that it's accurate. When your dealing with a situation where a couple of companies got together in "secret" for a super-private demonstration/screening of a new technology/technique it's anyone's guess what was agreed to, and what money may or may not have changed hands, and under what circumstances. We really don't know what the truth is at this point, for all we know the company that invented the tech decided it wants to try and get more money after the fact.
As far as how effective the technology is, well it seems to me that it's mostly aimed at people who "pirate" first run movies by sneaking in a video recorder or other kind of camera, record the movie playing, burn it onto a DVD, and then sell the lousy copy for $5 off of a blanket at a flea market or whatever. Theaters are supposed to be responsible for ensuring this doesn't happen, so I'd imagine the idea is that by obtaining a pirated copy the company could go after the theater for damages for not being secure enough.
It seems like a very "niche" security measure since honestly you neither want to force theaters to become so draconian that they chase customers away due to security harassment, or put the theaters themselves out of business so noone will show your movie. Good for a specific kind of case, but not all that good for general anti-piracy use. Meaning that I can't see a massive "OMG" fortune having been involved here to begin with.
