I don't think Voice is going after the Steemit social media model but rather after Twitter (that's what I heard). And from reading here how the platform should function, it seems to me like it aims at adressing serious problems within the Twitter ecosystem such as scamming through impersonification of popular people (the classic send and receive more Ethereum scam), being banned as if you are a serial spammer or else with no recourse (it happened to me, I was banned without knowing why and with no possibility to defend myself against no specific wrong doing), and maybe also being an alternative to the censorship culture of Twitter. It could explain why Dan Larimer mentionned Donald Trump who uses Twitter for his POTUS communications.
