Other than what you've kindly remarked upon, have you any idea what the motivation would be for a manufacturer to withold flight test data packages from simulator manufacturers?
Oh yes. It all boils down to money. The major OEMs are all positioning themselves for the major slice of the (future) training market and this is why datapack costs have skyrocketed to upwards of US$8M for the new generation aircraft. Makes any independent or even 3rd party airline operation totally non competitive.
(This is why LM bought out Sim Industries, Textron acquired Mechtronix and so forth so that their internal markets were also both closed to competition and protected).
Boeing and Airbus will eventually have more or less total control of the training market via data costs and be able to dictate training policy and prices and until then they need to ensure that the industry 'toes their line'.
Ask anyone about the "Boeing Model" and you may be surprised. This was the start!
