I'm starting to worry about the general public's understanding of the ramifications of this. When it first broke, I was pretty upset, and my partner (well educated, and with me long enough to understand some things about breaches) thought my concerns and anger at optus was excessive. It's only after I explained to her in some detail a few scenarios of what could happen with the information, that she asked questions about what we should be doing.
I think we'll be seeing fallout from this for years to come.
