More to the point, no one gets to decided what someone else should be willing to go to jail for or lose all their possessions for. Fuck that.
Whenever there is a specific entity that can be held responsibility by the people who can throw you in jail and take away everything you have, it's just a matter of time before those identifiable parties take action to reduce the likelihood they will be treated as such. That's human, and reasonable, and why decentralization is so important.
Steemit Inc. absolutely can be held responsible for what they show on their site, because they control it completely. They cannot however control the blockchain because the witnesses do that. (Neither can any one witness control the blockchain's content) This is why decentralization is so important.
