Sorry - can't see how it is dishonest - you are able to upgrade as long as you have a valid subscription - you were not compelled to have a continuous subscription and only need to have it valid if you wish to download or get suport. In otherwords if your subscription expired a year ago, you are not being asked to pay for this period.
This is no different to VB, FusionBB, PhotoPost or any other professional product.
