Tron did not buy a blockchain. They bought a company and an interface ( steemit.com). They may have a huge stake in steem. It does not mean the community will follow. I don't know a steemian who want to become an TRX-20 on Tron network. We want interoperable solutions and let token flow from one to another chain easily.
