They clearly do not want ANY non US players, but rather than say so, they make the terms so ridiculous that only the clinically insane non US player would still be interested.
This is dangerous for US players too, as there is very little coming in from outside the US with which to subsidise the very high costs and risks of running the gauntlet of UIGEA. This also means that should it become non viable to continue taking US bets, the group may fold, not having enough time to make a U turn in their attitude to non US players and recruit enough to keep enough cash flowing in.
Non US players do not have to wait and hope for Main Street to look like they want them, they have plenty of choice.
This was the sticking point that blocked them from becoming accredited after they had sorted out their 14 day pending period, and they showed no interest in making the necessary changes. Now we know why, they actually wanted to move in the opposite direction altogether.
Since they discriminate so dramatically between US and non US players, it would be misleading to accredit them on a general list due to the very different standards of service being offered. They might, however, belong on an accredited list designed specifically for US players as the 60x WR is merely "a bit high", rather than "excessive".
I think it's also a new "world record" for a WR, as it is applied across the board to ALL players except for one country. We have seen 100x before, but this has been limited to a small number of countries, and a small minority of potential players.
If they need to make it this harsh, it's because they are not making money on the older 100x WR for everyone else, and 40x for US players. The costs of the "insane" fees charged by the dodgy processors who continue to offer a service to bypass UIGEA, coupled with the dodgy processors that simply do a runner with Main Street's money (which means they end up having to pay players twice), must be a far bigger burden than the similar costs for dealing with transactions with non US players.
Other operators have coped by expanding into Europe, so that the rising costs and falling receipts from the core US market can be covered by the rising receipts and perhaps falling costs of servicing the non US market.
