the problems continually lays within the gamblers who react in a way that ends up detrimental to them, and that's why most casinos always advocate responsible gambling always on their platforms, gambling it's self if followed the way it aught to be , it's actually fun and not harmful but gamblers abuse it to their detriment because usually anything fun can definitely be addictive.
A gambling company also wants to attract professional gamblers because those gamblers will gamble on their site for a long time. Casinos also don't want gamblers who come in with a large bankroll and quit gambling within days. Because there is no long term benefit from them. So casino companies always try to support those gamblers those who gamble responsibly. Many also give several cautionary messages to those who fall prey to temptation. Now if gamblers are not aware but speak out against casino gambling companies I would say it is their ignorance.
Yes it is possible, but on the other hand it will also not rule out the possibility that professional gamblers may leave the gambling site if the casino has below average value according to them, and also vice versa if the casino is very comfortable and has a high percentage of trust then it is certain that professional gamblers will be there for a long time, because for them comfort and safety are the top priorities. And for the problem of the casino supporting responsible gamblers, in my opinion, it is a bit off, because what is meant by responsible is when gamblers are always not excessive in their gambling involvement in terms of the amount of budget or in terms of the time they use, while on the other hand the casino wants a big loss suffered by gamblers, which means that in my opinion the casino always wants gamblers to overdo it because then the casino will have a big profit, I think this statement is quite reasonable.
