Adapt or die.
You do understand that >50% of the hashing rate comes from Bitcoin mining farms located in China?
If they decide to not adopt a change then put simply *no change will occur* (as they will still be creating over 50% of the blocks making any 90% consensus simply impossible to reach) so chest beating is hardly going to help here.
This is not about politics but about finding a practical solution that will let Bitcoin grow without causing a collapse in the hashing strength or confidence in the Bitcoin blockchain.
So what if they can't get access to better connection is not other people's fault, instead you expect everybody else bend over to their wishes? how long you plan on bending over and take it just for the sake of it?
plus having more than 50% of hashing power centralized in one location is not good either and is not called " hashing strength " it's rather a weakness where the government can take over it if they wish especially in China. I see rather as liability for the network rather than strenghtSimply they either need to relocated to somewhere else or slowly die while dragging the rest of community with them.
