Recently, the steemit developers have taken over a bunch of accounts, most of which were taken over by a hacker, in order to return them to their owners.

Technically, this was done using a hardfork. Such a hardfork could also deactivate accounts, remove posts/content or freeze funds.
I was wondering, as the devs already proved this is possible and they can handle it, what would happen if officials force them to censor posts/content? Freeze funds? Are they still able to say no?
