Right, yes, it's illegal, but that's more an accident of legislature than anything else. Don't pretend that that gives it moral explanatory power one way or the other.

If I fail to lock my door, it's still immoral to enter my property and steal everything. Just as it's immoral to enter my unlockable mailbox and steal my mail.

I agree that theft resulting in exclusion of your access to your resources is very much unethical--copying mail does not result in this exclusion of access.

If you don't find it immoral for someone else to read your mail then honestly you should have no qualms with posting the entire contents of all your email addresses online for us to scrutinize as well.

I don't have to find it immoral; giving away that information freely is an act of charity I do not believe myself morally obligated to perform. Were you to come across it otherwise, I'd be a bit annoyed (as I would have to update various authentication mechanisms), but I wouldn't believe I ought to jail you or fine you or the like.

I make a bet, everyday, that the relative security of my systems is adequate for my needs. Some days I'm right, some days I'm wrong, and I bear no ill will for somebody that authenticates as me to that system--clearly, the error was in the system's scope and construction.

My problem with this world is people like you, who will be the first to scream fucking murder when some trivial wrong happens to you but you claim everyone else has no moral claim for not doing everything you deem appropriate. Get off your fucking high horse and learn the god damn definition of morals because at least knowing the definition might help you find a set.

I'm giving myself a 99% chance of being down voted, but put your money where your mouth is. I want to see your goddamn emails.

You know, if I could do so without giving away authentication credentials for other things, I would. That said, the cost-benefit isn't there. As I pointed out above, I don't have any moral obligation to provide you with information--if you gather on your own, hell, that's your business. As long as only copying has occurred, what does it matter?
