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)?
