A part of why I had a hard time with HF20, everyone saying that all the new user needs to do is "buy-in". It so went against everything that steem.io/steem inc was trying to do with steemit. But there is always the excuse we need to do it to control the spam. Kind of like the we need to do it to stop terrorism patriot act. Or any temporary tax increase, or temporary rate increases. Either steem blockchain is decentralized or it is not. After HF20, I would say not decentralized.
