Hi! Take a look at this blog post to have a better understanding: http://geekycoder.wordpress.com/2008/07/19/understanding-gpl-open-source-license-through-scenarios/ and these ...

I looked at the licensing options of DB4O and was really surprised there is no non-royalty option available, even with the pricey ''Enterprise'' version. Our application are usually sold on flat-fee distribution deals so we have no control how many copies of an application are actually sold and if I got the licensing model right, such thing is not ...

If this is the new business strategy for Db40 to only provide alpha (still buggy) builds for the community then it ...

Am I the only person who noticed this comment in the most recent newsletter? ''Starting with release 7.0, STABLE releases are only available to commercial customers'' I assume I've got the wrong end of the stick but I just can't work out what this is actually supposed to mean. Are the GPL releases now only available in bug-ridden form? Can ...

German, ''db4o is not experimenting in new legal ground here (for example MySQL has the same dual licensing scheme)'' Precisely the reason that I (and others) pick and choose GPLed applications and libraries based upon the organization in control.  As a GPL licensor myself I often prefer to direct people to Creative Commons' published ...

Well, I found the answers to my own questions: http://www.db4o.com/about/company/legalpolicies/gplinterpretation.aspx I'm sorry that there appears to be a disagreement on this issue, but I do feel that db4o's policy as written on the above webpage is a poor choice.  I understand that db4o feels a need to be profitable, but abusing Copyright ...
