It just important that people should understand that casino are not what we call the charity home,in other words not your Father Christmas vide if you should ask me.
It high time to see them also spend money too on ads,on influencers, on bonus, because they know they will gain more at the end.
I have come this conclusion long ago, casino are like other business out there whose owners strategize on the way the can make profit, the only difference is that they are gambling firm, but whatever, the aim is to make profit, and I dont think anyone should be bothered about that cause, casinos spend a whole lot of money in running promotions and, influencers are paid heavily by some casino too which you already stated , so all these shouldn't be for free if you ask me and without being told, every gambler should know that casinos are strictly business for profit making.
