>> Satoshi supported big blocks in his writings and empowered the pro-big block Gavin when he disappeared

Characterizing the arguments are big vs small blocks, seems wrong.

There appeared to be broad agreement that the block size needed to be increased, however there were 4 competing proposed solutions(BIP 100, 101, 102, 103), and consensus on which approach to take could not be reached.

Gavin decided to push ahead with BIP 101, and both Satoshi and Adam agreed that it was reckless to proceed without better consensus.
