From that article:

-in the current environment, where operators are tightening up their offerings by removing underperforming games from the floor, offering high returns in video poker makes sense. “If you don’t have any of that product, you won’t have that customer,” he says. “A lot of people mistakenly think I’m going to get rid of my 2 percent pokers because the hold’s so low, and put in a higher-holding video slot. They’re not the same customer. You just won’t have that customer."

I've always understood this. You won't get those VP players, as well as the friends and spouses that they bring along who may play other, more profitable games. But looking at the diminishing FP paytables we are seeing, it seems most casino operators don't understand this.
