In this case I think you have been unjust and exhibited what you have not been before. An armchair critic.
Ouch! That one hurt a bit. We are all armchair critics at some time or another. If Pprune readers were all afraid to comment on Pprune for fear of being labelled with the derogatory term "Arm Chair Critic" then what a boring website it would be.
The ATSB report implied the pilot did a good job to get his aircraft back on the ground on one piece. It took fast thinking and clever flying. No argument from me on that point.
Use of the full runway can be a pain in the neck in terms of lost time. On the other hand, a hundred successful departures from an intersection in a single engine aircraft must inevitably lead pilots into a false sense of security. That being so, it is up to the pilot to decide is it worth the small added risk not to use all available length for safety reasons.
