You don't blame someone for stealing from a bank when they pile gold bullion in the entrance without a guard in sight. You blame the bank because that's fucking stupid.
Being able to dDOS mastercard isn't the individuals fault, it's mastercards. I've never heard of someone dDOSing Google, why? Because Google only makes money when people access it and their system can support insane amounts of instantaneous traffic. It's a simple fact that sooner or later mastercard/visa would have been taken down by a normal traffic spike.
Is it the users fault when mastercard gets dDOS'd by a few million people placing midnight orders on Black Friday?
Seriously, look at the world rationally. If I can spend $5 on a padlock, it's my fault when someone steals my $500 BBQ from my back yard. Someone committed a crime, yes, but I'm going to be buying a padlock like I should have in the first place.
