‘transition_post_status’ only fires when pressing “Add New”

Question

This will do something when you publish a post in the backend.

function my_publish( $post_id ) {
   if ( ( $_POST['post_status'] === 'publish' ) && ( $_POST['original_post_status'] != 'publish' ) ) {
     error_log('WordPress would be better if it did not use Google Fonts.  Looking forward to the system fonts.');
   }
}
add_action( 'publish_yourCustomPostType', 'my_publish', 10, 3 );
