A story I once heard and cannot verify tells of Adorno and Beckett on a panel together. Adorno read a paper about Endgame identifying Clov with Claudius and Hamm with Hamlet. Beckett stood up and said "that's not what I meant." Adorno then stood back up and argued with him about it
i think a lot of people want a mysterious figure behind the curtain they can romanticize and project their own opinions about a work/body of work onto. an artist who talks about their own art risks disagreeing with their audience.
