Let's not call it a conspiracy. Let's suggest instead that, given the unwillingness of the MoD to follow what amounts to the compelling advice of the House of Lords Select Committee (which was effectively an independent judicial review), there is something politically sensitive lying under the surface, which renders a possible quashing of the negligence verdicts distasteful to the MoD/Government.
Whatever this sensitivity is, its publication has probably been deemed 'not in the public interest' and that is why we find ourselves where we are today. I hope that we don't have to wait until the 30-Year Rule applies in order to find out what this sensitivity has been.
