Im sure the post will earn you thousands, but if "astroturfing" means what i assume it means from the context ,your assertion is pretty ridiculous. I guess it does no good to keep saying it, but a transparent attempt to hide a readily apparent truth is only going to hurt the credibility of the platform.. if downvoting didnt effect others rep, id be doing it on this one.
And the part about centralization is intellectually dishonest. Steemit can ban users, hide their posts, and do all those things too.
