I'm not sure about BBN's original work, but it's worth noting that since
the passing of the Bayh-Dole act in 1980
dictated that 'universities may elect to retain title to inventions
developed through government funding' and 'universities must file patents
on inventions they elect to own', it's dubious that any such product of
academia as 4.3BSD, or their TCP/IP stack, would necessarily be open
source these days.
In the 60s and 70s, it was a necessity, since those inventions took
place under government funding, and until Bayh-Dole there was a more
powerful requirement that the results be placed in the public domain,
or under a non-restrictive license (if I recall correctly).
Not that the European academic situation is any better -- as far as I know
European universities are encouraged to assert IP ownership over research
that takes place in those universities too.
