If your stance is that a cartel in China has taken control of bitcoin colluding together to control it and no Nash equilibrium exists whatsoever, then you're in the bitcoin has failed camp already in the first place.
I agree with this. But I'm not sure what can be done about it.
Another problem is, what if the colluding miners become corrupt, and block size has been increased so much that no one can take control back, or at least compete? What if the corrupt miners then start deciding what functionality is and isn't acceptable in a release, to the dismay of the user base, exchanges and merchants? What if peer review and testing gets cast aside, and the software gets backdoored and full of holes/bugs with each release?
Is it still Bitcoin at that point? Do the miners really think users won't care if it becomes another bug-ridden, unadopted, centralized and controlled Chinese PayPal 2.0?
I've seen successfully-launched software projects absolutely crater after the initial brilliant team of developers was eventually pushed aside by a misguided & clueless management team, and replaced by a bunch of imbeciles.
