Ok, so we agree that the package recommend a virtual package which can 
be satisfied by either free or non-free packages.

Problem with that is that non-free packages can then satisfy the 
recommendation as _default_ alternative.

§ 2.2.1 of Debian Poilcy states:

Please fix vnc-viewer to list non-main packages only as *non-default* 
alternatives.
