I've tuned a lot of cars and I can tell you that this is only half-true. It applies more for vehicles with very basic modifications. When you buy a tune, you are often buying a service and expertise more than you are buying some drop-in product. Variations in hardware (intake systems, fuel systems, exhaust), fuel quality, and the intended use of the vehicle make many tunes a one-off job.
I've tuned a lot of (non-BRZ) cars and publicly showed parts of timing maps, AFR curves, etc. It doesn't matter as much as you think. Setups vary a lot, and ever tune is built off somebody else's work whether it's something the OEM did or some information obtained over the itnernet.
