The following are samples of some reactions:
Selective Availability (SA): Whether or not there are plans to
reactivate SA again, since US is involved in a major war
conflict, the answer is no. Media and others asking about plans
for SA are advised that the US does not intend to ever implement
SA again and is committed to preventing hostile use of GPS
through regional denial of service, thus minimizing impact to
peaceful uses of GPS. Regional denial of service means that it
is the intention to remove the capability to implement SA from
future GPS infrastructure. The US is committed to using
appropriate regional denial options to prevent hostile use of
GPS while minimizing the impact to peaceful users outside the
area of conflict.
Contrary to erroneous reporting by some parts of the media,
there is no plan or provision in the policy to shutdown the GPS
network

The following are comments from Mike Swiek, Executive Director,
US GPS Industry Council (See also attached Press Release):
Subject: Media Reaction to PNT Policy Statement
We have been receiving some media inquiries concerning the PNT
policy statement, which, unfortunately, seem to be focusing on
the issue of under which conditions the President would disrupt
GPS service, particularly over the US homeland. We feel that
this misses the larger and more beneficial points of the policy
statement, and have been responding along the following lines:
Concerning the portions of the Presidential policy statement
dealing with circumstances under which GPS could be denied to
users:
1) This is really “old news” as the US Government has always,
and prudently so, reserved the right to deny GPS in areas of
conflict to protect US and allied forces in theaters of
conflict. This is usually accomplished through localized
jamming, is not a system-wide denial, and is accomplished with a
consideration to producing minimal disruption to legitimate
users in adjacent areas.
2) The US has also, always reserved the right to deny GPS during
times of national emergency, but any decision to do so is only
possible at the highest levels of government, and can be taken
only by the national command authorities. The US authorities
fully realize how essential GPS is to national and global
infrastructures, and any such decision would not be made
lightly. To show how serious and unusual an action this may be,
GPS has never been “turned off”, and even continued to operate
during the terrorist attacks of September 11, 2001.
Instead, we view the real significance of the new policy
statement to be that it is a forward looking document that
demonstrates that the US authorities who own and manage GPS are
taking steps to ensure that GPS remains a reliable global
utility for legitimate civilian users even as the global
environment for satellite navigation continues to evolve. It is
a very constructive step. I have attached a copy of our news
release on this event.
