The moment that ned sold off the Steemit stake (what @aggroed [noted as the Neo Green stake), Steemit became a centralized platform.
ned promised to use that stake to protect the community premise of decentralization. that promise was desintegrated in the moment of sale.
and steemit will remain a centralized platform until that stake no longer exists
in this situation, a shit pie ;>
events have overtaken this discussion, and steemit, the steemchain (and following from there) steem itself is now a centralized concept
