You two seem familiar with the GPL with regards to WordPress.
Company A develops a website based on WordPress for Company B.
Company B claims that all the software developed by Company A for
Company B is proprietary information despite being mostly based on
Two examples where that I am curious about:
1) An established plugin from the plugin directory that had a bug
fixed by Company A during the development of Company B's website
cannot be released as it violates the NDA between Company A and
2) Company B developed a new plugin that is loosely based on many
other plugins (plus one that is private code who's owner gave express
permission to use it only for this plugin).
As I understand the GPL, the code does not have to be publicly
available, but if someone asks for it, the altered code must be
provided. Would this also apply to the new plugin, as it is developed
for GPL'd software? I know that wpmudev.org has plugins for pay, but
I can't seem to find their licensing information. I also know that,
to have a plugin in the plugin directory, it must be GPL'd.
Again, this is a purely hypothetical conversation, where I am looking
for your (and the rest of the hackers list) opinions. Your help is
