Well if the conversations were largely unintelligible, then I can see why the would leave them out of the CVR transcript. This is different from "censorship".
According to the BEA: "More items identified in the CVR could be added for better understanding of the event."
From page 186, of the official accident report, section 6.13 Accredited Representatives Comments, BEA's comment reference 45:
The CVR transcript is very reduced.
More items identified in the CVR could be added for better understanding of the event. A complete CVR transcript could be put in appendix. If not change the introduction which says: “the transcript is as follows:” into “hearafter is an extract from the CVR.”
