I'm not going to argue the merits of their business model. But the fact that numerous lawsuits have had mixed rulings indicates that there is at least some legal gray area here.
But if you know better then maybe you should just decree from the courtroom in your house and send your ruling to the AGs of all 50 states.
I don't think there are "numerous lawsuits" which have had "mixed rulings" it's really only a subset of the cases that have had anything remotely construable as positive to these companies. And again, that doesn't excuse their behavior. Bold of you to point to one court saying "I'm not sure" when the vast majorities of the others have said "this is perfectly clear, and here's why the other court is wrong"
Like, do you have any actual argument as to why it's not gambling, or are you just going to hang it on this plausible deniability? It's not like they knew the 3rd circuit would decide in their favor anyway, so I don't really think your point is the slam dunk you're acting like it is. They knowingly engaged in activities that most states consider to be gambling. They aren't even really denying that. They are just saying it falls under federal regulation, but the argument for that is so shockingly poor, it's hard to imagine how the 3rd circuit's decision could stand, but its only on a preliminary injunction anyway, so it's still not quite a merits decision. The third circuit said that by its own logic, Congress must weigh in on whether or not "bingo" is a swap regulated by the CFTC. If you can't understand how facially stupid that is, I don't know what to say.
