As intresting as this discussion about Midgard ownership is, I do not think it is relevant to this thread.
Midgard is "Free Software" according to their wiki & web page, and is actually covered under LGPL. This means that companies can used it in commercial products, and are not required to divulge their additions. You may notice the line, right on the wiki page linked above, stating directly: Applications developed using the Midgard application programming interfaces (API) can be copyrighted and licensed under any terms by their authors, enabling creation of commercial products and services based on the platform. So, in short: YOU ARE LEGALLY WRONG ON THIS MATTER.
