Look, I am not necessarily picking her side in the more general story, but it is apparent this paper submission story in isolation is super weird. It seems feasible that she was in the queue for getting the axe having engaged in prior fights with the company (some mention of threat of lawsuit, etc). I also acknowledge the account of story from her side was quite cherry-picked and actively strategic, if not deceitful, and it does not even seem that Jeff was a direct player in this saga. Looks the highest level person in the loop was Megan, not Jeff, and Jeff is simply dragged into the mix for the opportunity to throw a punch at his reputation. That, however, does not minimize the weirdness of putting the whole thing on this two-week paper submission policy.
For your last sentence, I think Jeff uses that 2-week policy to state that his position is "technically" right.
> Unfortunately, this particular paper was only shared with a day’s notice before its deadline — we require two weeks for this sort of review — and then instead of awaiting reviewer feedback, it was approved for submission and submitted.
If (to the best of her knowledge) she got approval through the correct process, and then an unidentified party opaquely removed the approval after the fact, I think her questions are justified.
Jeff's email explicitly says the paper was "approved" then submitted, albeit perhaps in one day. The two-week thing might be a policy but would be immaterial if it ended up approved anyway within whatever timeframe. It sounds like a red-herring to emphasize the time-in-advance; in any case the blame, if any, is to be on whoever flipped the approval bit and did not wait for other reviewers (possibly her manager?)
