His original idea was to swap Steem tokens for a TRON token to bring new users to Tron, it seems. When almost no one seemed interested in this plan, he announced another one (atomic swap back and forth between the chains). But it became obvious soon that he never planned to actually do this, so all the Steemit developers quit. I think his next plan was to sell off all the Steem tokens he got from Steemit as fast as possible. Mind you, I can't read minds, this is just my best guess. In hindsight, it's easy to say he didn't have a good plan for Steem or understand it very well.
