I can't agree with that statement... I think the world on the whole (especially the online forums and groups), don't have a proper understanding of what a "prototype" is, or appreciate the efforts it takes to get dozens of prototypes into the hands of customers for pre-release testing/driving. Vehicle manufacturers go through many development cycles and phases for every minute detail, many of which wouldn't be noticed by the customer, and some that would.
Keeping that in mind, allowing everyone to take and post photos of the "incomplete" aspects of a 3-generation-from-production prototype, while they complain about those aspects because it isn't identical to how production seems like a recipe for a PR "clean up" and correction of misinformation.
Photos were allowed of the interior of the vehicle on display in the tent (another PTO2), and countless engine bay photos exist online
