I haven't worked with their GPUs but I do work with their camera ISPs. I suspect that their reason might be that that seeing how to write software against the chip sort of gives away the secret sauce for how the chip works. I don't know if I would agree with that, but you can kind of intuit the design of chip based on its interface. How much values that provides is unclear though :/. Also, they do charge customers for that code and it costs money to support/customize it work customer use cases. I suspect that's another part of the equation.
