I thought you meant buy it originally. With the steem power taking 2 years to power down I don't know how they would buy it.
I guess they would buy the big steemit accounts which would give them influence over the direction. How eye they would never own it all.
No I mean that they could implement the same/similar reward system of where people are incentivized to use their platform. What I'm trying to say, couldn't facebook monetize their site for the users?
