It's only a matter of time before companies/governments start to join steemit and push their beliefs on people and censor those who don't agree if we keep the current flagging system.

You know when you see posts about something on Facebook (like a political post) and then you get all kinds of negative comments towards the poster because they are wrong. Well on steemit, as long as the poster has enough steem power, they could just flag all the negative comments and censor them all out. Sure they are still visible if someone wants to click to open it, but it's still censorship.
