Removed Mine filter and want to make All be default on Post page

Question

I've made a function to hide the Mine filter in the screen wp-admin/edit.php, using unset:

But when I click in the Posts menu (wp-admin/edit.php), it will not go to All by default, it still goes to Mine filter.

How to make the default to be All?

We can intercept what page we arrived at the very beginning of the load process (with load-(page)) and check if redirection is needed. See comments for logic.

add_action( 'load-edit.php', function() 
{
    global $typenow;

    // Not our post type, bail out
    if( 'post' !== $typenow )
        return;

    // Administrator users don't need this, bail out
    if( current_user_can('add_users') )
        return;

    // Only the Mine tab fills this conditions, redirect
    if( !isset( $_GET['post_status'] ) && !isset( $_GET['all_posts'] ) )
    {
        wp_redirect( admin_url('edit.php?all_posts=1') );
        exit();
    }   
});
