They have made moves, in the form of BIPs 100-104 and Lightning/Sidechains/Treechains. Project Apollo was not built in a day. We need to listen to the engineer and researcher Dilberts and Wallys, not the pointy-haired/headed bosses. Or
this might happen again.
Core dev dudes have no power to force Bitcoin's multi-year, multi-billion-dollar socioeconomic majority to do anything. Especially not a contentious (ie potentially disastrous) hard fork (ie catastrophic consensus failure).
Ah yes, the contemporary classic 'Zomg, Bitcoin WILL LITERALLY DIEEE if it does not immediately conform to my preferences' conceit.

XT is the default now and you have to deal with that. Just wait around and do nothing, do not support an increase in the block size on core, spend all your time and energy bashing XT, then watch when the day comes when we get 2 million new users in a week as the network panics into a 75% majority voting for XT, also known as THE ONLY REALISTIC WAY TO INCREASE THE BLOCK SIZE CURRENTLY AVAILABLE!!!
A vote for no block size increase on Core is a vote for Bitcoin XT.Please, fuck off back to /r/bitcoin_unsensored, or /v/bitcoinxt, or whatever vapid social media site you prefer.
This forum is the vapid social media site I come from and prefer thank you.
