They are not playing god, they are co-operating to use their influence the way they believe will help Steemit and Steem the most. There is absolutely no reason to believe that co-operation will stop or won't stop and restart with something else...perhaps even better given the evidence of co-operation right now. Enabling more people to experience having a meaningful influence on this platform teaches them something extremely valuable and is what will bring growth and value to Steem.
