I suspect the politics and the movement of bitcoin towards bitcoin cash is a short term storm in a teacup.
Most likely Bitmain just wanted insane profits for R&D to compete with the new Japanese mining hardware we keep hearing about.
I might be completely wrong, but if you look at the size of the hash power shift and the speed at which it took place, it does seem a bit suspicious.
