Why do current employees say they are former employees?

Just wondering why many of the people coming to the site to defend the company feel they look better if they say they are former employees who feel some things could be different but that many of the postings are from delusional, overacting people?

I put in my time and eventually moved on like most of my coworkers did. I wouldn't say any of them are bitter, but I don't know of any person I worked with who would actually defend the company this way and look back at their time here as an wonderful, overly positive experience.

I think before anyone makes the decision to leave ERAC on their own will, a certain level of reality sets in- whether they are a Branch Manager or RRM, where the blinders come of and they see the company for what it really is. That was the way it was in my Region anyway.
