Having experience on "both sides of the felt", I should probably play devil's advocate for the land based U.S. casino industry in a small way, at least in regards to their eventual decision to lobby against online gaming freedom.
I say eventual decision, because I know for a fact that a large group of the more forward looking Nevada casino owners became very personally invested in lobbying both the Nevada Gaming Commission and the Federal Government to set up a legal framework that would allow them to offer online services in the future. (circa 1994 maybe earlier)
Unfortunately, after several years, the only action taken by the NGC on the issue was to "clarify" certain laws in a way that precluded anyone who had gone through the long, expensive, and incredibly difficult process of getting a Nevada gaming license, from any involvement in "interstate gaming", under penalty of revocation of their Nevada gaming license.
The owners and some of the casino unions fought hard for several years, and spent huge amounts of money lobbying for the right to offer online gaming services, and continue setting the standard for their industry. But to no avail.
The reward they received for looking forward and attempting to plan for the future of their industry, was to be effectively be excluded from it.
Were I to find myself in their position, I would almost certainly do everything within my power to protect my business interests.
The U.S. casino industry has been forced into stagnation at gunpoint, by a bloated regulatory agency who's true mandate wasn't actually intended to act as a regulatory agency protecting the public's' interest. It was actually written to advance the federal governments interest in transitioning the larger criminal organizations which had developed during prohibition into tax paying corporations, with as much government involvement and oversight as possible.
Those old mob bosses are long dead,
casinos are businesses no different from any other, and should be allowed to succeed as a business.
We should all be writing to the Nevada Gaming Commission and flooding the mailboxes of every elected official in the state of Nevada daily requesting that they coordinate with the Gaming Commission to bring the gaming laws and the NGC into the 21st century, Nevada survives on gaming revenue, and the people of Nevada need to remind their public servants of that fact before Vegas and gambling no longer go together.
The U.S. casino owners have been foaming at the mouth and jumping through hoops for years hoping to be allowed entry to the future of their industry. It won't take them long to sweep most of these Euro sites aside if they ever get the opportunity.
