The thing that bothers me the most is that they know a lot of poitential employees have issues with the whole sector, so they try to give it a false veneer of acceptability. A good example of that was that both Paddy Power and Boyle Sports referred to themselves as suppliers of "risk-based entertainment" in their recruitment literature, something I found to be very sleazy.
I also know people who work for some of these companies and they tell me that all their talk about caring for problem gamblers is complete nonsense and that they actively seek ways to lure back problem gamblers who were able to quit.
It's also very weird that as governments around the world are cracking down on alcohol poromotion at the same time they seem to be encouraging the promotion of gambling. I would say gambling can do as much harm to a family as alcohol addiction can. I'm frankly shocked at the amount of gambling adverts there are these days. And so many of them carry the subtle sub-text that if you don't bet on your team then you aren't a true fan.
The problem is that people will gamble no matter what, so providing a safe way to do so is better than banning it. I agree with you that it's all about to what degree you allow gambling. At the very least I would ban advertising as it's effectively normalising something that most definitely should not be normalised.
