I asked kind of same question from him and he replied:
I joined the eosDAC team. I can't answer for Steem Power holders as to why they vote for me (that's up to them to answer).
He did said to came up with Idea of Steem as a DAC but we can all see his affiliation with EosDac more.
I still feel this way. It's up to Steem Power holders to decide who they trust to run the chain. As I explain here, IMO my involvement in other projects helps me bring important context and perspective here.
