I disagree that un-regulated will recover. I HOPE that it does, truly. I don't believe surcharges alone will be enough to bring un-regulated back. Many states are also going after offshores. I know my state(CT) already sent a C&D Letter to stop serving players from CT.
I've seen some industry guys that are even smarter than me say that DK is doing this because most of their customers are too dumb to leave or too loyal already. The ones who will leave are the ones that they don't want to serve as customers anyways.
