Steemit can, as they operate the Steemit.com website - and they can control what gets displayed. What they can't do is censor what is stored in the blockchain itself. Anyone is able to create their own instance of a blockchain viewer, to present the data that is stored in the blockchain. (Even Steemit.com's code base "condenser" is open source, so it could be used to produce a site that didn't censor, solong as someone was willing to host it.)
