There is nothing bad here for gambling entertainment. But gambling can be bad for those who abuse it. But promoting gambling is not a bad thing at all, I think promoting gambling is not a crime. Here many people spend their free time by gambling for entertainment. However, gambling should always be taken as entertainment and never used as a means of earning money. Many people find gambling easy and use it as a means of making money and end up ruined. Promoting gambling may be considered bad...
Promoting gambling shouldn't be considered a bad thing because you aren't forcing anyone to gamble but only promoting it. How many times has an advertisement being called bad because they're doing a promotion that can has addictions. Gambling is for fun and they're promoting for people to come and have fun.
If you decide that you're going to be the one with the greediness and what to make money but later lose, you don't have to be angry at the casino but next time. You have to be disciplined so you don't make the same mistake and lose money when you should be having fun. Gambling streamers are giving us something for entitlement, if we decide to try it ourselves without a force from them, they did nothing wrong.
Gambling can be enjoyed in anyway that you want to enjoy it. You can decide to use it for entertainment or to look for money.
