You are trying to suggest that Mark Zuckerberg doesn’t have a detailed knowledge and control over core Meta features, nor knowledge of the societal damage they can do?
Not sure how your response can be framed as 'Denying the antecedent'. :-/
Someone isn’t knowledgeable and responsible for every detail of every feature means they are responsible and knowledgeable for none
This clearly implies that sime blame is warranted.
