Police don't allow mobs to go around lynching people which is the type of behavior this change is encouraging. It's not about community self regulation either like it's being sold. This only empowers the largest wallets, of which there are few, with the largest ones being those who are proposing these changes. It's regulation by the 1% just like the mainstream media where billionaires use their power to produce propaganda rags for their cause and stifle dissenting voices. All of the changes I can see Steemit making are ones that favor their position on the blockchain, including normalizing a culture of downvoting behavior, and providing free downvoting mana so the largest wallets, most of whom are anonymous and could easily be multi-accouting, can more easily steer the reward pool into their own hands.
