That's because the "families" are intending (the article states) to sue the carrier and manufacturer, and it suits their cause to upset the investigation, despite the fact that these two organisations have by far the greatest detailed understanding of the technicalities.
But technicalities do not concern the lawyers concerned. Their interest is in winning. And I put "families" in quotes because they didn't decide to issue this statement, their lawyers decided to, wrote it, and told the families to say it knowing it would be lapped up by the press as the families' own thoughts.
The lawyers cannot believe the NTSB are professional enough to ask their own very penetrating questions to get to the bottom of things - incidentally, far more effectively than any lawyer in court. And for a much smaller cost.
