Another interesting fact is that is that is that Satoshi actually gets to decide what fork wins. People don't notice that in the case of a hard fork, Satoshi has a 1000000 BTC stake in both forks. He can choose to sell his coins in one fork, buying more coins in the other. - This alone will dictate the winner of the fork. So if Satoshi wants to stay at 1MB blocks - well nobody else can out-compete his economic power.
I've thought about this too. It was a relief to me to see evidence (e.g., the email from
satoshi@vistomail.com) that Satoshi was against the XT fork.
