A “no canceling anyone” promise isn’t very valuable if most of the threat comes from third parties—if you’re afraid to talk to me not because you’re afraid of attacks from me, but because you’re afraid that the intelligent social web will attack you for guilt-by-association with me. A confidentiality promise is more valuable—but it’s also a lot more expensive. (I am now extremely reluctant to offer confidentiality promises, because even though my associates can confidently expect me to not try to use information to hurt them, I need the ability to say what I’m actually thinking when it’s relevant and I don’t know how to predict relevance in advance; there are just too many unpredictable situations where my future selves would have to choose between breaking a promise and lying by omission. This might be easier for people who construe lying by omission more narrowly than I do.)
