Wordpress is very explicit about their intentions with their license:
Part of this license outlines requirements for derivative works,
such as plugins or themes. Derivatives of WordPress code inherit
the GPL license. Drupal, which has the same GPL license as
WordPress, has an excellent page on licensing as it applies to
themes and modules (their word for plugins).
<https://wordpress.org/about/license/>
They also note that add-ons that share processing and memory space but
do not copy code are a "gray area", and I wrote about this at length
here a while back:
<http://lists.runrev.com/pipermail/use-livecode/2013-December/196463.html>
Since I'm not a lawyer, and even if I were my opinion couldn't be
relevant unless I were also the judge presiding over this (and AFAIK the
definition of "derivative work" has never been tested in court, so no
such judge yet exists), I've taken a more simple-minded view:
I see two approaches to using other people's stuff, which we could call
"antagonistic" and "supportive".
An antagonistic approach seeks to use the work in whatever way one can
personally justify for one's own advantage, even if that use clearly
contradicts the intentions of the creator of the work. Such an approach
may prevail in court, or not, leaving oneself vulnerable to risk of
being found in violation of copyright. And in the meantime, while it
may provide some small advantage to use others' work this way, it
antagonizes those providing the very resources that makes one's own work
possible, turning would-be partners into enemies.
A supportive approach sees works made available to us under GPL as a
generous gift, and if we choose to use such a work we support those who
make our work possible by honoring their intentions. Given the many
ways code can be executed by other code, it may not be practical to
attempt to enumerate them all to attempt to reach a satisfying
definition of "derivative work", but if we honor the intentions of those
whose work we use we're unlikely to motivate them to take us to court.
On the contrary, we help popularize their platform and work together as
partners.
RunRev's view of "derivative works" seems consistent with that of
Wordpress, Drupal, Joomla, and others, so for myself, when I distribute
things for users of LiveCode Community Edition to use, I do so under GPL
or GPL-compatible license.
