Slysoft is a commercial enterprise, first and foremost. It is easy to lose sight of this when talking about their software as an instrument used by individuals to maintain their fair rights use of materials that they have purchased. If the studios can make the costs of doing business high enough, they can undermine the logical basis of keeping the company extant. Uncertainty of their legal position in Antigua might be enough to push them out of this business.
I'm not saying that will happen this time. They've probably prepared for the day when their legal status in Antigua is attacked by the movie studios, the MPAA and the AACS LA. But continued pressure will undoubtedly be the norm, especially if the AACS LA believe they can hamper any attempt by Slysoft to crack the new encryption seen on the Ultra HD Blu-ray format.
Eventually, the folks at Slysoft may decide that the rewards don't make up for the hassle.
And there are other economic forces on Slysoft as well. Fewer and fewer people are making backups of movies. I see this at many sites, where posters talk about movie decryption as something belonging to the last decade. Virtually everyone who has access to streaming sites have moved on, away from decrypting their own copies of movies. Buying DVD's and Blu-ray movies is itself a slowly dying activity, with many people using Netflix, Hulu and other sites instead. The large rental company Redbox is also showing this trend, with sales declining year on year, and their forecast for rentals is gloomy.
Combine the declining market and legal pressures and you can make the argument that Slysoft's future is just as dark. Breaking the upcoming Ultra HD encryption may give them a small boost, but that format will be a niche product, and I personally don't believe it will even reach the popularity levels of 1080p Blu-ray, much less the high points reached by DVD's and the surging interest in streaming.
