It’s regulations that keep a lot of them even marginally fair.

Sure, but those regulations aren’t about the addictiveness or whatever, they’re about transparency. If the odds of the game aren’t clear or accurate, they can get into a lot of trouble.

Businesses are motivated by profit, so they’ll do whatever they think will make them the most money. Getting businesses to behave requires making “bad” behaviors less profitable than “good” behaviors, and that’s an endless game of whack-a-mole, especially when a lot of laws just aren’t enforced consistently enough to matter, or the fines are lobbied down to relevance.

People are often motivated by pleasure, and replacing one from of pleasure (predatory games) with another is quite feasible, especially if you can point out how to find less predatory games. Making regulations to help this be transparent is a lot easier than making them go away.

So no, we shouldn’t try to teach businesses anything because they don’t learn. We should instead force them to be transparent and teach people to interpret that.
