I would not use the word 'Contribute' in clause 2, but instead use the
word 'Publish'. 'Contribute' implies more than just publication, at
least in common usage in the open source world. In addition, there is
no need to specify "to the public" in the requirement of applying this
license to changes; the license itself applies to everyone and cannot
be restricted to a subset without changing the license text, which is
not allowed by the license. The additional words will only serve to
cause confusion and uncertainty to readers of the license.
