The Democrat-Republican analogy was a brilliant way to describe the downvote problem.
I'd add that Steemit also has a downvote button, but the consensus there is that no-one should use it except in extreme circumstances because drama and toxicity gets in the way of making money.
Steem is a pure capitalist play, Blurt is a free speech platform and Hive is an oligopoly controlled by about 20 people.
