There is one way to reconcile the conflicting feeling about this: hard work towards noble causes doesn't guarantee appropriate compliance. These are 2 totally different things.
Considering that individuals and organizations working towards noble causes are very highly respected, they tend to receive less criticism than others, leading to weaker oversight too. So the risk of going downhill in safety compliance is very very real risk.
This is a trap that so many highly respected people walk into. You do something really great and the appreciating applause completely overdominates and suppresses the tiny voices of worry or doubt.
I am sure the pilot, Mac, was a hugely respectable man, with an unparallelled wealth of knowledge and a lot of hard work towards the noble cause everyone appreciated.
But this also gave him the "untouchable" status too, with high trust and lower oversight from the Foundation and his colleagues at the Foundation, including his co-pilot and his mechanic that day.
In aviation such status is of dubious value and increases the risk of death. .
As Scott points out in his video: at 19:42: "The important lesson to learn is that this can happen to any one of us, at any time, if we aren't working on it."
I think the foundation still deserve support, but everyone who donates should point out that better oversight on the chief pilots and chief IA mechanics must be implemented and maintained. And we should remain vocal about perceived incorrect practices, lack of engine run-ups, the logic of intermediate takeoffs, missing passenger briefings. Speaking up, just culture don't go against the "noble cause". They go against practices which threaten the work towards the noble cause. A big difference to remember.
