The whale is always going to agree with "STEEM IS GREAT!", because it lines their pockets.
This doesn't allow for any painful truth that might not be in a whale's monetary interest. Proving STEEM is rigged won't gain any traction because whales won't vote for it and even if 100 minnows vote for it, it won't make money for the poster, so why should anyone post anything critical of the platform? It's not worth their time.
