i have no idea.
Is it because this is yet another "Dan scam"? well it is a working scam, and it works without him for years. and tone of people were all waiting for the Voice, maybe people like new scams. Or maybe no one in steem is throwing around crazy amounts of money. they spend 25mil for ram to be prepared to announce possibility of requesting beta access account for voice.
maybe steem is blockchain social network for the poor. or maybe it has to much non HC crypto people on, so it has user base but not all go around spreading steem gospel.
i have no idea, i am just an user that clicks on steem front ends few times a day. never made anything great on/for steem, and never will...
