As financial decision it is questionable, as all companies and businesses always try to increase their profits, as long as it is legal to do so, this is rather a moral choice of the CEO of the company and a way for the company to bring more awareness of the problem of gambling addiction in their society and pretty much in all Asia.
Ultimately, the decision of asking for a loan in order to gamble is up to the gambler himself and it does not have anything to do with the bank or credit card company, responsibility of our money comes down to us and not our bank, we are the ones who need to be strong enough to realize what it is wrong and what it is right.
I applaud the integrity of this CEO, but it does not solve the problem of gambling addiction, people will always find sources of liquidity and loans of they search long enough.
