The article, and even the sources, seems to get the issues backwards, when arguing that the availability of the PSN vs. an online banking site makes it more vulnerable, and then goes on to talk about authentication measures. If your password is "pwnd" on PSN, you expect no sympathy if your account is compromised, also it very likely matters quite little (also, you can very rarely read your credit card details back from a compromised account). No so for your bank account, so the bank enforces obnoxious security on you. But this isn't what happened, this attack didn't go through the front end. PSN could have required fingerprints on every login, and they would have been no more safe for it.
