Can you elaborate what you mean by "nothing?" Why do they call it video poker?
The point is that insofar as the game replicates poker one can basically use that as a way to identify the difference between a "bug" and a "odd game rule."
In poker you do not win by having a good hand - you win by either having the best hand of those remaining at showdown, or being the only hand left. There is no "house" - all the players are equivalent, and playing alone is meaningless. When you play real poker in a casino, the casino isn't taking either side of any of the bets - the players are just paying the casino to play (real poker isn't generally very profitable for the casino - where it's offered its generally for "prestige" reasons, to bring in players who will hopefully play other casino game while they're here).
The only thing that these played-against-the-house games take from real poker is similar hand rankings.
Well, for one thing the "double up" option is not a part of standard poker. More conspicuously, physical poker involves a high degree of observation/manipulation/etc of human opponents and that is not a part of video poker.
Yes you remove the human element and change some betting rules but at its core video poker is a simulation of physical poker. The parent doesn't have much of a point other than being overly hyperbolic to discount the reality that there is certainly an argument that this was a bug and hack since the exploit sits clearly outside the realm of the game of poker.
