Please note that there was a typo in the text of the USENIX award acceptance speech we sent last week. It's been corrected on the web at:
http://www.gnu.org/events/bob-usenix-lifetime-accept.txt
The key issue was that "GNU Linux" was replaced with "GNU/Linux".
With English grammar, "GNU Linux" uses "GNU" as a modifier acting on "Linux". So it means either "the GNU version of Linux", or "Linux, which is a GNU package". Neither of those meanings is appropriate for the situation, so we don't write "GNU Linux" (except when we make a mistake). "GNU/Linux" is a way of saying "the combination of GNU and Linux".
The mistake was made because Mr. Chassell had written his notes to ease reading, not for publication and we missed on instance of "GNU Linux" when we published them.
We apologize for the confusion.
