It is simple. BS in fighting of keeping to the original white paper vs changing to solve the issues. Pissing competition over who appears right.
The original design was a master piece of game theory to bootstrap BTC but nobody expected it to become what it has and now the cracks are starting to show. Now at 120000 unconfirmed and climbing as people try to get out I think. I am in BCH now and enjoying the gains. If it keep growing at this rate it will overtake ETH in market cap quick.
