Over on cnet they have an Article about publius, a freenet like system from AT&T. When talking about the criminal uses of it they say:

But the AT&T developers say those risks are worth taking, in order to protect free speech.

I don't know about anybody else, but I'm not interested in their opinions, only in demonstrable fact. Ethics has degenerated into each side shouting their own opinions. Or, more commonly, each side creates a set of opinions to justify how they behave.

If the Publius/FreeNet/... developers want us to beleive their assertions then how about they try to come up with some scientific demonstrations of them. The fact that none of them has done this yet only leads me beleive that their opinions are merely a justification of what they want to do - not what they should do.
