Well said phgnomo. What happened to Steem is now a vulnerability to any DPOS blockchain. There are frustrations among the Tron community as well for similar reasons. Binance is Tron's top Super Representative (witness) as they use their user's trx to vote on Tron blockchain. They achieve this by paying users a bit more than other Super Reps do. But, do you really want exchanges calling the shots on your blockchain. No. I am of personal opinion that Steem would benefit by coming over to the Tron blockchain. There is a lot both chains can learn from one another.
