With the migration of content from http://www.ubuntu.com/community/ubuntustory/licensing to http://www.ubuntu.com/project/about-ubuntu/licensing, it appears that the documentation of the licensing restrictions for the universe and multiverse components was dropped. While there is an effort to drop these components from the archive, it is perhaps premature to drop the documentation of the restrictions prior to that happening.
Beyond that, I have a few issues with the following paragraph:
"This policy only addresses the software that you will find in main and restricted, which contain software that is fully supported by the Ubuntu team and must comply with this policy."
Firstly, all software in universe must comply with the same restrictions as that in main, but this wording implies that may not be true.
Secondly, this claims that all software in "main" is fully supported by the Ubuntu team. While this is a goal, this hasn't been true since at least edgy (Ubuntu 6.10), either for the entirely of the Ubuntu Developers, nor for the Canonical Ubuntu team (the set of software supported by the Canonical Ubuntu team is both a super and subset of main, and the set of software specifically supported by one or more Ubuntu Developers varies widely over time, without regard to components).
Thirdly, the wording implies that software not in "main" or "restricted" is not fully supported, which may or may not be true, based on specific packages (same rationale as for the second issue).
This should now be covered by the Unity licensing agreement.
