It would have been done by now if folks hadn't been intentionally driven away.
The kneecappening was intended to end steem's chances of success.
Somebody with power noticed that we could end the system as it was then known and issued orders that were followed, is my take on it.
Why else would a 2 year development walkabout and linear rewards be the 'solution' to why steem was failing to thrive?
Why were bidbots allowed to sell votes when that had be anathema all along?
Intentional kneecapping of an escape route, imo.
