Steemit.com is just a browser to the steem blockchain. If people don't like the flagging or reputation system on steemit.com, they are free to fork the code and build their own interface to the blockchain which has no censorship and pays no respect (visually) to the reputation scores. That, to me, is uncensored data. Claims can be made about the steemit.com interface, but since the data is open to anyone and the interface is open source, I don't see how it can honestly be compared to other completely closed source systems with no public data access.
