What is a decentralized system?

"A decentralized system is one which requires multiple parties to make their own independent decisions" In such a decentralized system, there is no single centralized authority that makes decisions on behalf of all the parties."

Pumpkin/Freedom oversees all top 20 "witnesses" by his powerful vote which chooses who gets the role as top dog witness (which pays 30,000-35,000.00 USD per year might I add).

Hence Steem is 100% CENTRALIZED or you could call it DecentraLIESed to be fair.
