I have been looking for plugins for my multisite and the problem I have is that most free plugins prompt users to buy their premium plugin that is licensed for single domain or they usually have a 3 site license bundle for some reason.
As far as I can see all plugins are considered derivative works as they don't run without wordpress and as such are GPL.
If I buy a plugin and add it to my multisite for all my sites to use can I get in trouble? If so what kind!
On the wordpress.org site they state clearly all themes and plugins are GPL and in the forums some people claim it has stood up in court as wordpress pushed a test case through.
Anyone have any insights on this!
