Why would he ever commit to anything? He despises the STEEM community due to the damage we have done (might have) to his relationship with CZ and his reputation in crypto. 

Id bet anything that he has developed a strong hatred for STEEM and would crush us if it wouldnt mean him losing money. 
He is a despot, simple as that, and having a rowdy bunch of idealists oppose him and win the PR game hurts his ego greatly. 

I see no way of witnesses working with him. There will always be this lingering fear that he might try something shady and im sure he will never let us put anything in code that will reduce his power over the chain to prevent that possibility.
