"Not likely he'd want to dump."
Regardless of our thoughts on that, I personally heard him make that statement in a recording of his conversation with the witnesses. It doesn't matter what I think about it. It's his statement, and I acknowledge the fact that he has sole agency over his investment decisions, over which I have no influence whatsoever.
It doesn't matter why he exercises sole control over Steem. It's just a fact he does. Steem is his personal possession in fact at present, and that's the reality that will continue to exist until and unless he and the exchanges execute code that prevents them from exercising governance. Further, code needs to be executed that prevents such hodlings from executing governance, which I find extremely unlikely anytime soon.
Any ability of @proxy.token or other community members to broker that possession potential to Tron is just as illusory as the decentralization of Steem has always been. The fact is that Tron has nominal stake to completely exercise sole governance of the blockchain presently.
The fact is that Steem is not now decentralized, and has only ever been allowed to appear decentralized by those with the stake to completely control it. It may have been an unsuccessful attempt to deploy DPoS to create a decentralized platform.
We can attempt to make a new platform that might succeed, or to attempt to make Steem successful, but presently it is not successful, and it's value is now only derived from the confidence the market has in it's owner.
Personally, I await the fork. I believe Steem is done.
