CN coins need a hard fork to change the algo or the CN algo will gonna die for gpu mining.
I agree that bitmain wants to compromize the main feature of crypto currencies by centralizing the power.
Not sure if they are doing it intentionally, but given their position; I think its a matter of inevitability. When you come up with an invention, you'd be stupid to not use it yourself. I'd say much of Bitmain's
profit comes from mining and not actually selling their rigs. But that's a hypothesis. Otherwise, they'd end up like KNC or Butterfly Labs.
Yeah but this isn't looks fair for the customers/home miners, the company manufacture a product and instead to sell this new tecnology item, use for itself dominating the entire network and when it not profitable anymore or if there is a high risky to turn useless, the company sell this product for a damn $12k.

This is like nvidia/amd use the video cards for mining and sell when the company figured out a new gpu with new tecnology and more powerfull turning the previous item almost useless. I think that a company must sell the product with guaranted benefit or just don't sell it, like a real mining company that mines petrol, gas or something else for itself and dont sell their machines when it is not profitable anymore.
But crypto/mining is unregulated over the world so we can't do anything, there is no laws for cartels.
