This is a bit like suing McDonalds because you are obease. Or rather suing NBC because they carry a McDonald’s commercial which lead you to eat too many Big Macs, making you obease. It’s an extremely hard case to prove. Plus you have to start with proving that online gambling is illegal in the first place. As far as I am aware, there are no online casinos headquartered in California, they are all offshore, where it is perfectly legal. Sounds like they will be going down a path of trying to prove who has juristiction over the internet, which is next to impossible to decide.
