The answer is simple - one very talented developer that I personally encouraged to get to know with the steem blockchain. He is not known in the community, because he had never posted or voted anything before. Therefore, there is nothing to be told about the person behind this, because no one knows him here. Yet. Stop spreading some crazy conspiracy theories please - there is no such in this case. Eight months ago he wasn't even aware of existing of the steem. Then he learned and now he is presenting his product to the community. That's all the "mistery" you are trying to solve.
