So basically everyone in the US that points there miners to a Chinese pool is basically screwing themselves and the whole BTC community outside of China.
I don't see how it this bad?
Bitcoin have nothing with this. You can mine it or buy it.
Only if you don't like China economic growth supported with this mining farms (but this is insignificant at the global level). Bitcoin is good because you really don't need to know who was previous owner and where is mined, this is point!
If you do not see how it is bad, then you do not understand the importance in miner incentive and the model of decentralization. If three pools are responsible for 75% of mining hash, to me, this is centralizing the control of incentive for mining. The simple fact that companies like BitMain (Chinese) are making the software in their antmining products read-only is also sketchy. You buy hardware that remains in control of the largest mining pool? You cannot change default ssh passwords? Pretty sketchy.
