The team behind TripleA and the witness server will NEVER involve nor confirm any action or code that could freeze or limit the stake of anybody on the Steem blockchain.

Such a statement seems a little unnecessary and possibly naive. On a decentralised blockchain where such actions would require a super majority of top witnesses (17 out of 20), there is close to zero chance anyone's stake would be maliciously frozen. If any top witnesses planned such actions they would not remain top witnesses for very long.

If the blockchain comes under threat, it is the duty of the witnesses to protect the blockchain. Under these circumstances, a temporary restriction to particular actions might be deemed necessary until the threat is removed.
