It doesn't matter who started the team. It doesn't matter who puts his name down as "head cook" on applications. It doesn't matter who stays up all night feeding logs into the fire, nor who cuts the meat. It comes down to what you, as a team, think is right.
Does any one else on the team have any assets? Are you willing to lose them and the assets if you make decisions without them?
Does any one else on the team contribute money to pay for things besides personal food and drink? Are you willing to lose them and that money if you make decisions without them?
Does any one on the team help with the work in any way? Are you willing to lose that help if you make decisions without them?
At the end of the day, very few teams are legal entities and membership on them can be incredibly fluid. If your teamates chip in and want a say, then they should have it. If you don't want to give it to them, kick them all out and fight over who gets to use the name. It really only matters in KCBS for TOTY and competing on the same day or at the same comp.
