Sun's goal was to purchase and let the Steem community continue to govern themselves why he inserted resources to better the platform and increase exposure. Justin never attempted to take control of Steem blockchain until witnesses performed a soft fork and froze his funds that were purchased legally as you or I would purchase coin. I am on Steem at least twice per day to play Splinterlands. I was stoked to heard about Sun's purchase as I knew it would finally help Steem become a decentralized blockchain.
