I know little about Tron, but it is a little funny that we have a link with dlive again. He also owns Bittorrent, but I have not looked at that much recently. I think it's good if it brings a whole new audience to Steem and some fresh publicity may revive some dormant accounts. There is a risk he could compromise the integrity of the blockchain that could reduce freedom and put rewards at risk.
I assume it would be possible to do a fork that excludes specific witnesses, but we would need enough going with it to make it viable. The markets might decide that makes Steem worth a lot less. I know a lot of people were not impressed by Ned. Maybe Justin can be a better leader. Some have pointed out that him being from China is a risk.
