>From the look of Stallman's message, it seems as if he thinks copying software is totally free, which in reality it costs a bit more than just plain free.
That's often true. (And even if it doesn't cost you money, it may take some of your time.) But I don't think that changes the issue. Zero-cost or small cost isn't the crucial distinction. The crucial point is that copying software is practical and feasible for computer users in general. We can and do copy software, unless someone goes out of his way to stop us. In the case of hardware, it would mean it is too expensive to copy... which it could be... so does that mean freedom to copy something became irrelevant as the cost of copying becomes relatively expensive? When something is impractical to copy, then the question of whether we are free to do so is purely academic, and I see no reason to fight about it. When something is feasible to copy, then the question of whether we are free to do so makes a real difference.
