What you did was to alter the node object that was passed into the form builder as an argument.
Instead var_dump the entire $form array and look for keys that do not start with a dash. Those are the ones that will finally be rendered. Keys starting with a dash control how they are rendered.
Take a look at the examples in the docs: https://api.drupal.org/api/drupal/modules%21system%21system.api.php/function/hook_form_alter/7

The only way I can see that happening is if the form array is being changed back after my hook, so I tried changing the module weight to 99 (via mysql) and clearing cache. No difference.
