I'm exceptionally surprised that the contents of an internal BA investigation or report into the crash have been published or even released outside the company at all. AAIB have taken charge of the investigation and executorship of the MOR, and that normally means no details will be published until they conclude. A little like being sub-judice.
[That of course excepts any directly related safety issues required to prevent re-occurrence.]
Someone is playing fast and loose inside BA methinks, I'd love to know what AAIB thought about this latest information!
