There are many sides to capitalism - Steemit is a part of my favorite trend of decentralised platforms. For example, where Uber failed, even more decentralised Arcade City stepped in. It's a market solution to a problem created by government regulations - it connects passangers (customers) with drivers (service providers).
We can "vote" with our resources (not only money) to support project that we consider useful and fair. If you don't like Walmart, you should avoid shopping there and take your money elsewhere. The freer the market, the more choice we have and it's up to us how we use it.
