In response to another criticism, yes, my phrasing is imprecise. It matters to some extent whether you take precautions to secure your own computer -- doing so will reduce your level of risk, and you should do it. But you cannot assume that if you do this you will be completely protected. We live in a society, and that means that we have already given out a lot of personal data which is now stored in conditions which are about to become a lot less secure.
