In this case, for instance, Netflix still has a relation with their partners that they don't want to damage at this moment, and we are not at the point of AI being able to generate a whole feature length film indistinguishable from a traditional one . Also, they might be apprehensive regarding legal risks and the copyrightability at this exact moment; big companies' lawyers are usually pretty conservative regarding taking any "risks," so they probably want to wait for the dust to settle down as far as legal precedents and the like.
Anyway, the issue here is:
"Does that statement actually reflect what Netflix truly think and that they actually believe GenAI shouldn't be used to replace or generate new talent performances?"
Because they believe in the sanctity of human authorship or whatever? And the answer is: no, no, hell no, absolutely no. That is a lie.
