Well, you can be sure that they made enough money from bitcoin cash.
They mined bitcoin cash even when it was unprofitable to mine, because later they made an organized pump and they were managed to push it to 0.5BTC at most of the exchanges which is completely crazy.
Bitcoin cash is being completely controlled by the chinese strong players, it's a centralized coin that is being used for manipulations only.
I feel that we will see Bitcoin's attacks on the part of the Bitcoin Cash creators more than once. I fully agree that Bitcoin Cash is completely controlled by its Chinese creators. I was surprised at how its price began to grow and approached half the price of Bitcoin, but then realized that it was only made artificially, and not because of the popularity of people.
