Regardless, what's the difference between a Chinese mining monopoly and a Russian mining monopoly except for whether you have a personal vendetta against the Chinese ones?
It's not a monopoly when two strong entities exist at the same time...it's called duopoly...and when they're not working together it's called competition. And competition is good for all of us.
OK, well I hate to break it to you, but several groups other than BITMAIN are already major groups. So I suppose you should be questioning the OP's point about the "Chinese mining monopoly".
My view is that
any group controlling too large an amount of the hashrate is bad, whether that's BITMAIN or the Russian government. The difference, however, is that BITMAIN only has temporary power over their amount of hashrate, because if they did something really malicious the miners could just move away from their pools.
I suppose all this stuff with mining pools is just an inherent flaw in Bitcoin anyway so we'll have to sit back and watch how it pans out.
Anything that removes China is a good thing.
By which you mean anything which competes with BITMAIN, rather than things that "remove China".
