if you download the supersonic bundle, its notice.txt says:

• Magnolia Standard Templating Kit
  License: GPLv3 (http://www.gnu.org/licenses/gpl-3.0.txt)
  License: Magnolia Network Agreement (http://www.magnolia-cms.com/mna.html)

That is incorrect. STK is CPAL licensed. Please update this asap.

Same is or should be true for

• Magnolia Standard Templating Kit Demo Project
