I agree completely. The same applies for movies that are "sold" encrypted: the decryption key could be sent only to verified ("trusted") clients, so in practice, the GPLv3 draft is not even close to avoid usage of DRM systems above which a user may run GPLv3 licensed software. The user could change the keys on the hardware and run any binary and even watch encrypted movies on his modified GPLv3 licensed program... provided he has the keys required to decrypt them (e.g. movies encrypted by himself).

This seems to be a real loophole in the GPLv3 draft.
