we do follow arch, as we do basically a configured arch install, with some tools in addition. Development for EOS is open for contribution from anyone.
We do not have this one leader.
Decisions are more democratic, our idea is to create a structure and development that do not depending on one persone or group of persons so that it is more community driven and can survive passing persons or personal changes.
