> Where are you getting the idea that we're reneging on the decision to Open Source Lightworks?
I think there may be a sort of lexical misunderstanding.
"Open source" is seen as a keyword, almost a trademark of a certain software production/dissemination philosophy. It is related to the slogan "free as in freedom".
Maybe the misunderstanding comes from the fact that the licensing terms to which you are referring appear, to some, to be more related to the other type of freedom ("free as in beer"), where the product can be obtained for free, but it is not available for modification by the (so called) "community".
However. as the OpenOffice.org experience shows, an *effectively* hybrid model is possible. Theoretically, all of the office suite is open source. Practically, the core part is essentially developed as if it were a proprietary project, while other parts (documentation, translations, plug-ins...) can be contributed by external developers. Moreover, I have the feeling that most popular "open source" projects work like this: GIMP/GTK, Inkscape, Scribus, KDE...
I see a very strong *commercial* potential in a project that is actually open source (a customer-friendly company), multi-platform (hardware- and software-environment-friendly), flexible in licensing (starting at cost=0.00, bank-account-friendly), flexible in usage scenarios, although specialized in function (pure editor).
In any case, I think it would be in the company's interest to take advantage of possible external contributions to the project itself, just as it has been for the documentation on this same website. Contributions could certainly be reviewed and not included if not up to standards, so it would not be a matter of quality.
