I think the fact so many users are leaving is bothering them already. - Maybe even more then if they stay and blog complaining.. The moment they have less traffic is the scenario that they are afraid of, not so much people complaining- that is only annoying.
The sign of revolution is a symbol for "left to contribute in a better place". In the end only people that are fine with Steem and its rules will stay. Those are bloggers who probably dont like Hive eather way. If so, they will know it is there. Hive is pretty strong already in terms of community and coin to not become a secret hidden place.
