Interesting twist here is that after being criticised for storing all this sensitive data even years after customers left, Optus has pointed out that they are required to do so by data retention laws the government itself created.
If you accept perfect security is impossible (everyone should) then anybody creating data retention laws (ie: the government) really has to also assume some level of responsibility for the risk that the data is going to leak.
