over 80% of the fullnodes are located in China, strongly insinuating that bitmain is running the show, aka centralized.
But that is just the nodes, which is of course vital. It can and is planned to be hardforked, which by definition makes it centralized.
I've noticed some stories circulating about ppl working in the bcash group abandoning ship due to criticism not being allowed, especially in relation to fake satoshi. There is too much to be critical of, in his case aswell as several others(like Ver.. ) so it makes sense that they demand obedience in that regard.
