What kind of mentality is this? This is clearly not a drupal mentality to add the footer link. In case you haven't noticed, Drupal is one of the few open source application which doesn't add a footer link.
Drupal 6 by default adds a footer link. It can easily be disabled...but it looks like the footer link clearly is the Drupal mentality. Not that it necessarily needs to dictate what Ubercart does anyhow, but it was interesting to see.
