I am all in favor of the witnesses implementing a softfork to change the username of "justinsunsteemit" to "buy_my_shit_coin" or "trons_is_a_scam".
You are right, he abuses his own chain. It is a centralized "chain"[ https://cointelegraph.com/news/tron-co-founder-and-cto-leaves-project-alleging-excessive-centralization ], yet he fraudulently markets it as decentralized. He should be arrested, prosecuted, and convicted for his fraud. The tron chain offers us nothing but tiny 200 byte transactions [ https://github.com/tronprotocol/documentation/blob/master/English_Documentation/TRON_Protocol/Mechanism_Introduction.md ], far below the 65536 byte transaction size limit that enables true dapps here on steem. The token swap implies that Justin Sun is planning the death of the steem chain. A token swap also means a new minting, and a new minting means he could print as many coins as he wanted for himself since he wants to centralize everything. Theft through dilution. If he had his way then he or Chinese Communist party would censor what we say on the platform by reducing steem to how own personal private database. Tron [and China in General] is famous for deleting things it disagrees with: https://medium.com/popnetwork/banned-from-the-blockchain-an-ethereum-developers-tale-of-migrating-to-tron-248a0d215c92 . Justin Sun is persona Non-gratis. If the only thing Justin sun can offer us is free marketing, I think we can get far more marketing if we as a community let all of the cryptosphere know Justin Sun for the Cancer that he is and that Steem Chain was the chemo. It was the mouse that roared.
The cryptospehere should one day punish Mr Justin Sun and reduce is Tron tokens to zero for its crimes against those who invested in what they erroneously thought, as Tron marketed, a decentralized future on it. The streets of San Fran should welcome Mr. Justin Sun. The streets are full of shit, the San Fran elites doesn't like it, and Justin Sun completely loves peddling it. Enjoy your future Justin Sun for your first real job in your entire life-it is your calling. And you are more than welcome to use that mouth of yours to clean it up.
You purchased an inferior Dapp Mr. Sun-not the chain. Go lick your wounds, and get the hell out of here.
