I believe the above provides an excellent description of how the OVPL
provides a balance between using open source to maintain a sustainable
business while providing the benefit of that sustainability to the wider

Its often easy to forget the benefit that open source software receives from
a business-oriented benefactor. I am quite sure that the in most if not all
dual-licensed projects, the wider community gains from consistent
development and improvement by developers employed by the company 'driving'
the software. Often this will make up for a decreased degree of
participation by the open source community. Many of the great open source
products that we use today have used this model to become what they are.

IMHO, to create a precedent that would see such a model as 'non open source'
would be an unfortunate development, particularly in light of the growing
interest in open source by closed source software players.
