Message integrity is essentially a binary issue; either we defend message integrity as described in my Message Integrity chapter, or we do not. There is little or no middle ground because any crack in the integrity can be exploited to do nearly anything, thanks to the patch hole. While it is not strictly speaking impossible to imagine an exemption that can not be so exploited, one can still question why it's worth the risk to free speech.
So while this is theoretically a degree of freedom, if we are to maintain our commitment as a society to the principles of Free Speech for all, we must choose to defend message integrity, and thus this degree of freedom is already chosen for us by our pre-existing ethical values.
