alt Hacker NewsI don't think my article makes any claims that one can undo sharing. What I'm saying is that we benefit collectively from being able to untether data from applications. It's the same logic as https://stephango.com/file-over-app but applied to the aggregating web applications.
Share and you can't control what everyone else does with the data. Hence, untether is a non concept. In the sense that that data has now lost it's uniqueness. You can untether all you want. Copies of it will be subjected to any kind of tethering and transformation. So, if your point was about control, forget it.
