And really, what you're talking about is a balance. Very few people actually believe that anyone has a total responsibility to always submit to punishments for laws. Nobody argues that people who helped slaves escape from their masters should have turned themselves into the state afterwards. Nobody argues that a North Korean dissonant should hang a sign on their door announcing their intentions to defect. Nobody argues that before the Boston Tea Party everyone involved should have said, "well there's no need for these disguises, the point will be the same regardless of whether we go to jail afterwards."
And of course in the opposite direction, nobody argues, "well, you had a good reason for running that red light, so it's perfectly reasonable to run from the police when they try to pull you over."
What you're really arguing is that leaks about a company's immoral behavior don't cross the line where people have a right to defend themselves from having their lives ruined. The reason GP disagrees with you isn't because they don't understand that orderly societies require laws. It's because they think it does cross that line.
Personally, I trend towards agreeing with them. It is very easy to tell other people that they should just buck up and accept unjust consequences as a result of helping me. The reality is I (and society as a whole) benefit a lot from whistleblowers. Given that whistleblowing is already a very dangerous process, it's not clear to me why it's in my best interest to heap additional social condemnation on top of that.
Believing either (a) that people should hold the law abover their own values, or (b) that people should only be judged on adherence to their own code, are not ways out of the conundrum - they're just a particular set of values.
Neither of these things is reasonable. Am I supposed to start an election campaign if I don't like the law? Am I supposed to move my whole life elsewhere?
No, undermining the powers that be -in this case by leaking- is the right thing to do.
1. There are three (not two) choices in modern life: follow the law, break the law, break the law with anonymity. The last still carries risk, but not nearly with the certainty of the second.
2. Between this and your replies downthread, we have to be clear that "society" consists of three parts: government, citizens, and capital (aka corporations). All of these influence the creation and enforcement of laws.
Because of the last, I would assert that in modern capitalist democracies, it is possible to break the law yet be in complete moral alignment with the citizens of your society.
An example would have been the original protests against the Tea Act of 1773.
