Why is meaningful trustworthiness not included of Free Software definition of “computing freedom”?

In this youtube video excerpt (minute 8.33-15.55) from Panel 2 of the Free and Safe in Cyberspace conference, that I organized 2 weeks ago, in which Richard Stallman and myself debate about IT trustworthiness and free software. The entire panel video is also available in WebM format here.

In such excerpt, Richard Stallman said that computing trustworthiness is a “practical advantage or convenience” and not a requirement for computing freedom. I opposed to that a vision by which the lack of meaningful trustworthiness turns inevitably the other four software freedoms into a disutility to their users, and to people with whom they share code. I suggest that this realization should somehow be “codified” as a 5th freedom, or at least very widely acknowledged within the free software movement.

That’s one of the main reasons that lead us to establish the Trustless Computing Association.
