It's simple. Providing a better service than a $3000 a year newsletter and getting the voluntary upvote weight of 6% of the total pool requires another few percentage points worth downvotes to "Balance things out"s and prevent "Reward Pool Rape" so that the rewards will be distributed to the "Little guys"s and post about their righteous flags to gain few thousand USD worth upvotes.
It's the commies on steemit you think they know what each person deserve and use their power to allocate rewards as they fit by negating the + votes by using - votes for a Zero sum effect.
