In the interim while w await the final report with a full analysis of the data by qualified experts, any number of "what-if" theories can be offered by those who watch from the sidelines (PPRune etc.)
A good writer can link selective facts together in a cohesive fashion to promote any number of theories. Apparently you found one in your referenced report. However there are numerous more theories being discussed on PPRune in these threads and any other good writer need only to cherry pick what sounds plausible into a competing conclusion with your source.
The more profesional don't rush to judgement of promoting a theory until all the facts have been vetted among the experts.
