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.
