Section 15, paragraph1, sentence 1:

"Notwithstanding any other provision of this License, if you modify
the Program, your modified version must prominently offer all users
interacting with it remotely through a computer network (if your version
supports such interaction) an opportunity to receive the Corresponding
Source of your version by providing access to the Corresponding Source
from a network server at no charge, through some standard or customary
means of facilitating copying of software. This Corresponding Source
shall include the Corresponding Source for any work covered by version
3 of the GNU General Public License that is incorporated pursuant to
the following paragraph."

Nowhere does it say that the version you _use_ must prominently offer
all users interacting with it ... only your modified version must do that.

Not sure why they did that, but there it is.
