Centralisation of 'truth' is never a good idea. Information needs to be free in order that we can have all voices heard and all angles can be considered. Just look at the way that totalitarian governments and dictators effectively control the people with an engineered and biased version of the truth to see why everyone must be allowed to come to their own truth freely.

Steem is designed to allow self policing by those with the most stake, in the form of downvotes which ultimately lead to a loss of potential to be seen and to receive rewards.
