Because I have actual experience on that this is the only think I will speak about publicly: for me, the experience was entirely the opposite.
It was a lot of fun to write with Bond and at every point of the writing process I felt taken seriously. https://twitter.com/vorewangji/status/1310123063623647234

When I look back on the story we have worked on together, I can see both myself and Bond in it. I didn't count how many words were written by me and how many by Bond but tbh that's not what I feel is the most important thing about a collaboration.

It was, in all regards I remember, a collaboration.

Why such an "exposure document" is considered necessary I can't say.
