As I understand things:
- Black Boxs went to Canada for analysis.
- Canadians cannot reveal what they reveal, under ICAO rules, because Cameroon has not given ‘permission’.
- This means that they may (I emphasise may - I have no idea), be information of great relevance to 737-800 pilots contained in those black boxes.
- We won’t know until Cameroon, the world's leading aviation power and authority on civil aviation - gives its ‘permission’ to the Canadians to reveal all.
