Why specifically computing devices? Everything else can be used against you without your consent. I mean obviously you should be allowed to encrypt your stuff if you want to, but I don't see what's so inflammatory about this example. This guy did give his consent when he got a pacemaker installed, presumably so his doctor could give him better treatment by analyzing its data.
