Uplinker, the "wagging finger" was to represent the sort of treatment which can and has been meted out to flight crew after incidents such as this.
I sincerely hope that this crew does NOT experience such treatment after the facts come out, but Der Management can sometimes lapse into this mode especially post high profile events like this one.
Also, IF the practice of scheduled maintenance on 2/2 engines on a twin has crept back into operation because G-OBMM was so long ago, then I like to think those responsible for that policy be subjected to a very public shouting and finger-wagging session!
I didn't know that a simple exercise like daily inspection oil top-ups required cowlings open? The last time I checked a dipstick on a '56 involved a small access panel halfway up the side, but I wait to be educated.
