I don't blame them, but the thing is, they sell their dignity in order to promote gambling, maybe because the offer is too good for them to refuse, but the concept of them abandoning their dignity and ignoring the fact that they could have a bad influence on their viewers, even if they put a warning about being responsible in gambling, the thing is, people or viewers will for sure be attracted if they see the streamers getting or winning too much money.
The problem isn't to promote gambling industry, rather it's how they are promoting gambling industry. If there are warnings telling people about the risks of gambling and guiding them on how to be responsible gamblers, there isn't any issues. It's a legit, transparent and fair propaganda. The problem is when these streamers lie to their public and give the wrong impressions about gambling. A common example is when they say gambling is a source of extra income and that people should gamble to make their wages grow into larger sums of money.
That is, they sell gambling concept as a method for poor people getting out of poverty without working harder or educating themselves to have access to better paying jobs. And that is disgusting, because as we know, for most people the more they play, more money they are going to lose. Consequently someone in poverty will remain on poverty forever that way! Meanwhile, these streamers have their pockets full of money thanks to the delusions and misconceptions they promoted on their social medias' channels.
