I do though still reserve the right as a witness to adopt any hardfork that I truly believe is in the best interest of the stakeholders and platform, and in absolutely extreme situations - that might include freezing somebody's account.

Anyone can fork Steem at any time, as @smooth has put it, nothing is lost but something new is created. It's up to anyone to choose which fork they would support and could even support both chains.

When a witness publically support a fork that as little support then this witness is at high risk of getting vote out.
