Poker lost quite a bit of steam when regulations were tightened up a couple of years ago and USA internet gaming was definitively ruled a no no. Lots of players pulled their $$$ out of their accounts then. It snow balled from there. Not many people can afford the 10k buy-in's at most poker tournaments. Less internet players mean less super satellite big time tournament entrants. Less entrants, and less possibility of becoming an entrant, translates into less interest in the game. It still goes on, and people still wager online, but just in less numbers than before. Since more people have easier access to internet gaming than they do to B&M casinos, the game is contracting rather than enjoying its previous unhindered growth boom. It'll come back. Ebb and flow.
FWIW, the software referenced is not a very prominent feature at any of the cigar sites I know it to be featured on. A niche diversion, at best, and not a cheap one given its generally low number of participants in proportion to a board's overall membership.
