I'll just quote you here for context, people can make up their own minds:

I would like to make a commitment to you:
If Steemit, Inc. stops the full power downs of all of their accounts and returns them to their normal power down rate prior to the first disbursement of the current power down cycle, I personally commit to you (on chain) as a witness that I will not implement, support, or condone any hardfork that affects the balances, keys, or security of any of Steemit's accounts on the current chain.
