Wow they could have planned this misadventure a bit more carefully. Having decided to do this stupid destructive thing, they should at least have resolved not to admit they did it on purpose. The general public would have much more sympathy if the story was "after lengthy investigation, we've determined that the bug only affects counterfeit products... we have sympathy for all victims of counterfeiting." Instead, they've gone for "in your face, you cheap bastards!" Honesty is not always the best policy, especially when you're evil.
They're being somewhat evasive, but it's clear that this is intended as a deliberate anti-counterfeiting strategy.
