On the other hand wordpress.org also says the plugins are bound to the
GPL[1]. They also link to the Drupal FAQ[2] which also describes this in
great detail.

It is also interesting what FSF writes about plugins for GPL licensed
software[3]. I would say that ownCloud belongs to the category where the
plugins need to be GPL again:

"If the program dynamically links plug-ins, and they make function calls
to each other and share data structures, we believe they form a single
program, which must be treated as an extension of both the main program
and the plug-ins. This means the plug-ins must be released under the GPL
or a GPL-compatible free software license, and that the terms of the GPL
must be followed when those plug-ins are distributed."

This describes very much how ownCloud apps works.
