Comment on "Sound Modes broadening in Quasicrystals"

Recently de Boissieu et al. proposed an explanation for the broadening of acoustic modes observed in quasicrystals (QC). It is the transcription of a well-known model used for glasses. We raise two fundamental objections against applying it to QC. After the text of the Comment we report the methodology that has been used to thwart the publication of this Comment, which is perfectly valid.
