UPDATE: The linked post is now updated to say that the author was given advance notice:
Through some careful wording in his post on First Movers, [Anthony] Ciolli left me with the impression that he was sandbagged by this development when in fact he chose not to respond to an email to him that informed him of what YLJ stated its plans were. That said, having seen the letter YLJ wrote to Ciolli, it is clear that YLJ's plans to change the essay were not an invitation to discussion or negotiation, since the letter opens with "We are appalled by the postings on AutoAdmit.com that threaten and defame our classmates, and we have decided to disable our website’s link to www.autoadmit.com. This letter describes the effects of that decision and our reasons for it."
Here's what I take to be the upshot of the saga: YLJ gave advance notice to Ciolli and had Ciolli wanted to find a solution better than what was proposed, he could have tried to have done so but he didn't even bother to respond.
