The initial purpose was not wrong. Witnesses failed to keep SBD to what is was supposed to be. And, I believe, a few of the whales on Steem used this flaw to manipulate the price. When the price goes up, there are less rewards for the minnows because the bigger fish post and upvote more.
Just because people are looking for short-term gains at the price of the long-term health of the system, doesn't make them correct, it makes them near-sighted.
