That makes sense. The 'MIT license' (about which Jerry Saltzer did a note for
the October-December 2020 issue of the 'IEEE Annals of the History of
Computing', available here:

  https://www.mit.edu/~Saltzer/publications/MITLicense.pdf

and which mentions that it was initially done for the MIT PC/IP code) only
applied to the MIT-written applications, not a 'derived work' (to use the
intellectual property law 'term of art') based on Bell code.
