If Bitcoin Classic wins then Gavin is going to be the "benevolent dictator" (which I think has always been his desire).
Do you want him as the overlord?
It isn't the code that is the issue - it is the hostile takeover that is.
Gavin has cleverly now gone with something that only changes the one thing (but more importantly puts him back in charge - after they take over who knows what will happen).
I can tell you with absolute 100% certainty what will happen. People will use the code they agree with. If developers of any client add code that users disagree with, they won't update to the new code. Ergo, there's no such thing as a dictator in Bitcoin, benevolent or otherwise. There's also no such thing as a takeover, hostile or otherwise. There is only code and users freely choosing what code to run.
Bitcoin is and should be whatever its users define by the code they run. If you don't want people to have a choice, a closed-source coin would be far better suited to your goals.
