The other story you are referencing is "this was an expensive education in which you have learnt to not do stupid stuff".

This is framed as "this was an expensive learning opportunity for us to learn that we have a gap in our systems that allowed this downtime to happen".

These are different sentiments! To me the above quote is very explicitly the latter and directly refutes the notion of "this was expensive training for you" by stating that it's impossible for an individual to apply that learning in a way that would recoup the loss.
