I am cautious of any "facts" that come out this early, but if flight controls were failing, that seems like an excellent reason to get on the ground as soon as possible (and a likely explanation for why the landing was not smooth). I don't see any reason to call the pilots stupid, and dumping fuel or spending time burning it off would not be normal or necessary under these circumstances. It was a tragedy, and only time will tell what exact sequence of events led to it. It is possible that pilot error was a component, but it is far too early to tell.
I think plane systems should be able to function after lightning strike. And initial failure of all systems - defect of the plane construction (SSJ-100). It's just my opinion, not official words.
