"...they judge us based on our actions."
I don't think that's how this works.
We've seen how the exchanges will proceed when the Steem community is opposed by Sun, and it's not going to be based on our actions, but their financial ties, and Sun has significant influence in that regard.
Regarding forks, we'd better have a preferred option ready to roll out when Sun's is ready, because we will likely prefer nearly anything to whatever Sun implements when he gains consensus.
We'll see about exchanges in the aftermath, once Sun and Steem are a separate entity. Without a community to imbue his token with value, regardless of their prior relationships with Sun, it's likely his token will be dropped eventually by exchanges, and that will not have any bearing on a new token the community fork supports, which will have the value of the use case that provides.
There's no reason that exchanges wouldn't list that coin, as long as it will make them money.
Thanks!
