What I indended to say with the above was that in the hypothetical case Justin Sun decided to shill Steemit while letting Steem fade into oblivion, he wouldn't be able to do that because it is impossible to advertise Steemit without advertising Steem.
Why would Sun want Steem to lose value when he is the majority share holder by a huge margin?
After replicating Steem on Tron he might want the original chain dead.
Who says the man is sensible. After all, he's jeopardizing the reputation of Tron by actively meddling with Super Representative elections with his large premined stake.
How do we know he's REALLY playing with his own money? Some of these Musk-like guys get all their funding from the major PTB... And any platform that can currently be used to question those same PTB--even a little bit-- will always be a threat to them.
