It seems pointless to keep urging people not to speculate after a crash for it is the most common (you could call it natural) thing for pilots and engineers to do.
We all know that nothing is definitive until the report is out so, those of you getting upset about other people's opinions should try and pipe down a little.
I don't think anyone has come out saying "this is the absolute cause of the accident" so, live and let live.
These suppositions are what many are interested in reading about and, as CRAB has said, a good many professional guesses have incidentally proven correct in the end, meaning that such idle gossip might not be all bad after all.
