Thank you for your hint. As i am not sure, would this work then for posts with the category “news” to be excluded from publicize:

/**
 * Do not trigger Publicize if the post uses the <code>news</code> cat.
 */
function jeherve_control_publicize( $should_publicize, $post ) {
    // Return early if we don't have a post yet (it hasn't been saved as a draft)
    if ( ! $post ) {
        return $should_publicize;
    }
 
    // Get list of tags for our post.
    $tags = wp_get_post_cats( $post->ID );
 
    // Loop though all cats, and return false if the cat's name is <code>news</code>
    foreach ( $cats as $cat ) {
        if ( 'news' == $cat->name ) {
            return false;
        }
    }
 
    return $should_publicize;
}
add_filter( 'publicize_should_publicize_published_post', 'jeherve_control_publicize', 10, 2 );

I would also know that, as some news are not to be shared on social media.
