There are a couple points in that article that highlight the differing interests involved.

The article states that players have a major role in spotting cheats. While players probably help spot many cheaters, they lack the sophisticated detection resources possessed by casinos. They also lack control over the rules and procedures. A casino can ban a suspected cheater. Another player can't.

The article also says that the system "works" because cheaters have been caught. Yeah, it worked for the casino - but not for other innocent players who had jackpots canceled.
