While it's all speculation, it's a hell of a lot better than what the government does with these baseless terrorism claims which they disguise to look like facts. At least going through these scenarios (fire in the cabin, electrical damage, loss of cabin pressure) might lead to some clues worth pursuing. I do share you pessimism a bit though because I believe since we haven't found the plane by now, it's probably at the bottom of the ocean. There might be an accidental discovery in the years ahead though. And with a little luck they can reconstruct a credible scenario from the engine telemetry... it wouldn't be the first time.
