No.  It is well known that BBN packet switches are used for the Defense
Data Network, which includes Milnet and what used to be Arpanet among
other things.  But BBN has also for a long time sold wide area networks
to other government and commercial entities around the world.  Michigan
Bell's public X.25 packet switched network offering is built on BBN's
C/30 and C/300 switches.
