This leads me to think that Free Software, while a good, ambiguous ideal, can't be made into a strict moral system because it's impossible. Stallman is right on both counts. Software running on another computer isn't unfree to you, you just have to be careful what you send to it. And, there's really no difference between that and having a server running proprietary software in your living room. Or on a guest user account on the same computer. Really if you treat proprietary software as a dangerous black box it's no different from interacting with the outside world. So, unless you never send data to the outside world, you can't reach the ideal.
