Reading the Boorman script didn't mean he was involving himself in its production. At that time he already sold the rights and wouldn't have been any position to change it regardless.
Like, what exactly are you trying to prove? Do you actually think JRR Tolkien would have directly supported Rings of Power the same way Simon Tolkien has? Cuz I flat out disagree if so. JRR Tolkien was much more conservative with his work, while Simon is much more liberal with the handling of the franchise.
