As a miner I think Bitmain is something to be feared. No one really like miner centralization. However, after much thought and analysis, I believe Bitmain is a necessary evil.
Bitmain is required to help boost prices of Bitcoin up. They sell hardware and prevent other competitors from entering because they will actively re invest back into cryptocurrencies. I can't say the same for other mining companies and it seems better than giving money to Nvidia and AMD in the long term.
I've written a full article on my thoughts here:

We are anti asic and we need new algorithm to prevent asic centralization. Asic has created by a greedy person. It can't be trusted. I hope anything will move to the POS system.
