Suppose Wikileaks developed installable software that embarrassed the U.S. government. Would their key have been revoked, making it impossible for anyone to run their software? Yes.
Also, slippery slope. Cmon.
That which does not exist cannot be abused. I'd much prefer a world where authorities cannot disable software, not a world where they merely don't.
That's not fallacious slippery slope reasoning. It's an argument for structural and technical rather than merely moral, ethical, or legal impediments to abuse of authority.
I've got to disagree with you there. Every piece of modern technology out there has the potential for abuse of authority - but you don't crap on the tech wholesale simply based on that alone. The moral/ethical/legal impediments are how you rein in abuse, not by hamstringing yourself.
Perhaps you posted this in the wrong story?
