Maybe just search for better games then. There's plenty of mobile games that don't rely on gambling. Most are indie, but there are really some gems in there.
The reason those games are so popular is that they're inherently exploitative. I have no issues with predatory app developers being priced out of business.
Unity cares. This whole fuckup is Unity trying to further monetize mobile games and get a stranglehold on mobile game advertising. Console/PC games are just collateral damage.
If this costs Unity enough money it might work. I'm not holding my breath but stuff like this has a better chance of working than PC indie devs abandoning Unity does.
