The basic argument is sound, and is worth repeating. My take is that it is impossible to achieve 10^9 flight hour levels of safety by pilot training alone. Systems which pose significant risks must be engineered out at the design stage. Relying on imperfect pilots to catch those rare but catastrophic outcomes is not a valid strategy.
IMO the chart does not contain information that cannot be conveyed in a single well written paragraph. This is sometimes given the derogatory term 'chartjunk'.
Someone may not have liked it because it is hypothetical, and gives a gloss of fact, in a thread already full of rumour and speculation.
