Do we know the investors say in this? I don't know if the faucet is given away from the investors money or the casinos own money so I can't really say anything specific about it.
However, if it is just the casinos money then it would be obvious that casino itself will find a way anyway, they are currently saying they are winning against the abusers so there is nothing to worry about and they are actually doing the right thing for themselves, if they are the ones paying for it, why would we worry about it, they will definitely find the correct way. But if the investors are paying for it, a bit of things change in that scenario, maybe there could be some sort of referendum where investors could decide what should be done about it since it is their money involved.
