> If Apple was similarly accused of wrongdoing by the IRS, and told to backpay taxes that they were supposed to have paid, would you still feel similarly? But that's not what's happening, really. If as an individual the IRS wrote to you and said "look, all your tax returns in previous years were in compliance with the law, but we've now decided those laws were wrong and you owe us more money" you might understandably be a little annoyed. There's a reason that in most (but not all) cases we don't allow new laws to be retroactively applied - because we recognize it to be unfair.
