They run rigged games in predatory ways.

I don't know what you mean by this. Games have a fixed margin which is usually disclosed or can be computed (exactly like the 0 and 00 in the roulette skews the odds in the house's favor if you want to do just black/red). There are then whole chapters in national regulations about random number generators to ensure the odds are correct and the games are not rigged (i.e., a game certified for 98% should have that outcome). Are games designed to have the house win a 2,5,7,9% margin? Sure, but this is out there in the open, there is nothing to "rig" in the same way having 0 or 00 is not "rigging" a game of roulette.

They happily let organised crime launder money for a cut.

At least in Europe, you get audited quite often and AML regulations are very tight. Laundering money via online gambling companies with their cooperation seems quite unlikely to me (and inefficient, possibly, but I don't know).

They fight regulations designed to reduce problem gambling.

Some do, but not all, and not in all cases. Addicts are bad for business for gambling companies, or at least for some of them, moderate long-term customers are generally better (and require way less effort).

I don't know what you know about gambling, I definitely think that the ethics are questionable, and I left the industry when I could also for those reasons, but the company I worked for was not very bad in this regards. Maybe you worked/had experience with some of the shady ones (like those who operate in illegal markets using a single license from a random tiny country)?

Who's "they"? I don't know much about the gambling industry but if it's anything like any other industry then it's not a centralized monolith but many independent business. As long as the founding principles aren't inherently corrupt (and in the case of casinos they aren't. Nobody is forced to play and everyone knows the house has an advantage and in the long term is guaranteed to win. Because of this it doesn't make sense for the house to cheat and risk getting caught, it will win anyway.) there is no reason to think that the majority of the industry engages in criminal activity. This is a massive generalization.

There are ways to cryptographically verify bet integrity, but that's not important. The point I was trying to make is that people should have the right to make their own decisions, even if you disagree with them, even if they're objectively wrong.

You haven't met most people. :)

I presume you don't consider yourself to be a part of the aforementioned majority? Do you believe it makes you superior? Do you believe you know better what's best for them? Do you believe you must protect them from themselves, even at the cost of their self-determination?
