I'm thinking more along the lines of blocksize increase and their limited internet capability. We've been discussing Chinese farms fighting the increase. If the increase happened anyway they will be forced to take some kind of action. I do agree that it would be good for Bitcoin if they were out of the picture.
In a way the Chinese miners are hindering any further progress that could've taken place already.
They should've not set up mega-farms in a country with restricted internet to begin with but their greed of making money didn't stop them from doing it and now the rest of community needs to suffer just because they can't access internet is their own fault and not anybody's else. I say if they can't keep up let them sink for good.
They can go on and make a Chinese version of it and trade it among themselves and the rest of us can progress further without any limitation and a better decentralization. it's a win win strategy

That works for me. It would be kind of cool if they refused to upgrade, the difficulty drops massively and westerners are able to mine again for a reasonable profit. lol
