You keep insisting this, but I don't agree its that cut and dry.
Current literature on the subject suggests otherwise when calling
code that is "designed as a library". Regardless as to whether it is
statically linked or otherwise. Creating a derivative work is not a
technical definition, it's a legal one. Most of the reading I've
done outside of the GPL FAQ agrees with this.
Drupal's strength IMHO relies on its community, and defining the
risks we're willing to take in terms of technical semantics feels
like a step in the wrong direction. I agree, that the SMF bridge
case takes it too far. Distributing non-gpl code using the drupal
infrastructure would be a step backward for us also. I think we
should continue to feel free to distribute code that says it's GPL,
no matter what, but not try and second guess lawyers on what is
considered a derived work or not.
If the drupal foundation decides that it want's to go after people
who might bundle and distribute drupal core with other non-gpl code,
I'd probably be supportive of that. I would not be supportive of the
foundation going after contributers who develop modules to integrate
drupal with proprietary systems and release those modules as GPL,
whether we think they're wrong or not.
And with that, I think I'm done with this thread.....
