The only thing to decide was if they would let the hacker get away with at the time 15% of the whole supply. If they did that it would have endangered the decentralization of the eventual proof-of-stake switch.
So they decided to kill it outright?
The distribution of ETH was less decentralized before the hard fork than afterwards. 15% of the whole supply in one hand is quite a concentration in the distribution.
So the solution to save "decentralization" was for a centralized cabal to literally rewrite history?
Given that this incident resulted in the Ethereum/Ethereum Classic split, the "centralized cabal" was not very effective. The community voted with their feet and many went to Ethereum Classic.
Your argument is circular; “code isn’t law because I’ve redefined the word ‘law’ to explicitly preclude it”.
