It's not just that a few people haven't acknowledged the technical issue though - it's also that 95% of mining capacity is now held by a handful of people and they don't want to change it either.
with the mining capacity mostly in the hands of china, i'm not surprised of DDOS attacks and censorship behavior against XT proposals. bigger blocks would put out of competition the majority of chinese miners unable to support the network with their crappy uplink and criminal attacks keep the situation unchanged, they are going to milk the cow as long as possible
