Nothing of value is being suppressed though.

Who decides what is of value?

One of my last posts as well as a chess post (a self-composed chess problem which cost me hours to produce it) got downvoted as retaliation for criticizing a top witness (a very big part of all downvotes is given due to different opinions or retaliation purposes).
HIVE is completeley centralized and dominated by early miners and former bid bot owners who, in addtion, vote each mutually as wtinesses and decide which proposals will be supported.
Furthermore, they lend each other their posting keys and delelegate stake to sock accounts to mask their actions.
I call that an oligarchy which is - if at all - only slightly superior compared to Justin Sun's monarchy.

(Apart from that I don't share the political point of views of many users who are complaining here, but completely share their criticism concerning the downvoting on and centralization of HIVE.)
