A few problems with your article
The article you mentioned was about Detroit casinos, which have nothing to do with Las Vegas.
The barred players were all long-term "comp whores". The casino was giving out very generous inducements to keep the normal suckers coming in. These people were playing positive to very low edge VP, hitting the "double points nights" heavy and taking advantage of every promotion possible (ie - smart players). The casino realized they were not making money off them.
The casinos (being the true slime buckets that they are) barred a group of these players. Bad policy? Yes. Bad PR? Yes. But technically nothing wrong with it. They realized they weren't making money on these players.
Reminds me of the story of my friend who owned a bar. Around every Christmas he would put on a huge feed. Free Food, Free Booze, Free Entertainment. Kind of a big thank you to all his customers for their business all year. People would come from all around as he put out a huge spread. After several years, he finally stopped. He was standing there one year at the party and had some drunk he didn't know hanging on his shoulder yapping in his ear. He realized that a lot of the people there he had never saw before. Some of the people only came to his bar once a year for the free feed. Most of his regular customers, who he was trying to thank, didn't come anymore to the party because it was so crowded.
As a result, no more free Christmas party at the bar. He didn't want to have to stand at the door and not let people in, trying to inforce a 'regular customer only' policy. The same thing would happen at casinos. Let everybody in and cut back on comps for everybody, or let them try to sort the customers out and offer more liberal comps to the real suckers (and some people will play the comp game of trying to look like real suckers).
I only worry that the corner grocery store never realizes the only time they see me shopping is on double coupon Thursdays, and the only time I ever buy Pepsi from them is when it is on some super sale, etc. ....
