Copyleft Compliance: Minor rewrite of strategy & firmware liberation
This rewrite should improve the stand-alone nature of these documents
and allow for better integration with other summary text and
announcements on the website.
Note that they have now drifted heavily from the original formulation
of the items as grant proposals.
