The decentralization part comes from the blockchain i'm assuming. Same as every other coin. It's in the fact that everyone has a copy of the ledger and not one single person is in control of the money. I don't think they really meant that the coin is a democracy that people can vote on to make changes.
Anybody knows, how to make a poll here? At the start of the topic?
The thing is, Verge community doesnt let you discuss or vote for anything concerning PoS/PoW
