I have mixed opinions. I agree that they conclusion is much more clear than the single slide implies. However, the slides do a poor job communicating in many other respects. For example, on the first non-title slide four separate acronyms are used, an only one is defined. (Incidentally, it's one that also has another, different, acronym within industry - M/OD => MMOD). Maybe everyone in the audience already familiar with these terms, but maybe they're not. I think in this case clarity should trump brevity. I think the original site has a particular, biased point of view but also that NASA can often do a poor job communicating.

The part I'm grappling with is how they came to that conclusion despite the "flight condition is significantly outside the test database" acknowledgement as alluded to in the original post. To me, this sounds very much like Challenger in terms of drawing conclusions without hard data to back it up. Easy arm-chair quarterbacking in hindsight, I know, but it seems the through-lines are psychological in nature, not engineering or technical problems.
