What are the exact exit criteria of the fork?

Different witnesses may have different expectations. So far, there seem to be only two witnesses in the top 31 who do not run the soft fork (timcliff and jesta). Of these, some may be content with Steemit and Tron giving more information such as a roadmap or vision, plus stating what they will be doing with the stake. Others may have a more drastic view and think that the stake should not have been Ned's to sell for profit to begin with, and should instead stay with the community.

So how would it be resolved if there are different views for what the criteria should be? It's quite simple. As we learn more, some witnesses may be comforted by what they see and choose to not run the soft fork, then eventually there'll be a majority who do not, and it will be reverted.

My criteria is first that we get a concrete and detailed answer by Steemit Inc and Justin Sun themself. If their answer is drastically different to the original promise Steemit Inc had, then I think it would be fair for the community and stakeholders who invested time and money into Steem on that basis to have the time and availability to leave before such changes are applied. If they promise to treat the stake the way they did before through not voting, then I would expect them to use the "decline voting rights" operation which removes those functions from an account. If they do go along with the opinion that some have that the stake they have is supposed to be used for community growth and further decentralization, then I would hope to see some action performed that make this "trustless" through either a donation to the steem.dao, or a foundation.

The important part is this: We need to know if the previous conditions for the stake still apply or not. And if not, what the new conditions are. And then be able to move on from there.

I agree that there is a risk here in terms of perception. I also think Tron and Justin Sun offers a unique opportunity for Steem to gain some much needed marketing talent and financial resources. So I am motivated, and can promise, that I will do what I can to pursue a positive outcome for Steem, and hope for a situation where the two projects can find mutual benefit and create a win-win for users and stakeholders on both sides. Therefore I will be spending a lot of time and effort the next few days in a diplomatic way to try and make that happen.
