set visibility to public by default?

There is a filter available for this. It is call document_to_private.

If you wish to revert to standard processing, then create a file called wpdr_revert_private.php in the directory wp-content/mu-plugins.

You may need to create this sub-directory. Then copy this code into it:

<?php
add_filter( 'document_to_private', 'revert_private', 10, 2 );

if ( ! function_exists('revert_private') ) {
	/**
	 * Reverts the document status from private.
	 *
	 * @since 0.5
	 *
	 * @param WP_Post $post     link to (new) global post.
	 * @param WP_Post $post_pre link to clone of global post.
	 */
	function revert_private( $post, $post_pre ) {
		return $post_pre;
	}
}

The doc-comments are essentially those from the filter itself showing its parameters. The result will be that you get a draft post displayed that you can publish after you have uploaded a document file.

Hope this is of use,

I’ll mark it resolved.
