The part of the gambling companies being out of US jurisdiction is very true. That’s why I think they don’t have to stop accepting US gambling because they are regulated by other laws that permit it.
The problem here is that THEY VOLUNTARILY decided to not accept US gamblers anymore. That’s the case of 888 and partygaming and rumours are that playtech and microgaming will follow. That means that you will lose commissions from your US player base. Although they may be willing to gamble, they can’t because online casinos will not accept. This means that you will lose new US players and ALSO your past players.
So the most important part of all this is not the bill itself but the casinos VOLUNTARILY blocking US players, when they have a choice since they’re based outside US.
