Like I've said, I know for a fact that the network was handling all player funds cross-cage processing (settlements between skins on the network. Common practice else every skin would end up owning money to the network or, like you've said, take deposits but don't settle with the network. Thus, networks always handle the processing unless a skin is at VERY good standing with them. Thus anyone who thinks he's owed money, contact Enterra.
That is definitely not how its handled. To acquire a standalone licence is a 1 time payment of around $10-$20K for this kind of poker software, honestly, anymore than 10 and your just throwing your money away. Ontop of that it depends what kind of partnership deal you close. Typically these platforms charge like a % of net-rake (5-10% depending on volume). They do NOT manage the funds in anyway shape or form. That way they take no responsibility for player funds, regulations etc.
my opinion is that most of these brands actually go in with good intentions. But they have no idea what they are doing and when they realize they are at a lose of $20-30K and its time to pack their bags, they take whatever change is left inside. I guarantee you they didn't make millions.
On the other hand, why should a player care? His funds are frozen/stolen or whatever. Very sad!
