Exactly. If Gavin gets the top 4 exchanges on board and pools, user complaints won't matter (sadly it is like this, and the average Joe can't do anything).
Disagree. Gavin cannot do it if majority of users are against it. Every (official, registered) exchange will have to announce their decision beforehand (otherwise they could potentially be facing legal actions). Same with cloudmining businesses and pools.
So theoretically speaking, if pools/exchanges etc announce that they'll go with the new fork, then people, who want to stay on old one, could just move elsewhere. Therefore pools/exchanges probably will check for the average joes' opinions before making any decision.
(worst case scenario) This brings even more concern, if Theymos does not support the changes and they get forced we will end up in a very bad situation. Everything will split and the fight for survival will start.
Why is Theymos that relevant in this case?
