That is certainly a posibility, although I disagree that the witnesses started this war. As far as I am concerned the signal that the Tron foundation sent on their official cummunications of their intent to turn steem into a tron token was the first shot.

Now, the posibility of a fork always exists but only Steemit Inc has enough clout in the public's eye to claim that they represent steem, especially from the side of the exchanges. I don't think that anyone outside of our own little world knows of the existence of the Steem Foundation (they haven't exactly made an effort to let the outside world know that they exist).
