During the early days of packaging, there were a set of packages which
would pull things from the internet to 'complete' the build. This led to
non-repeatable builds, and in some cases security problems when a
precompiled blob on sunsite.unc.edu was compromised. There were also some
sets of code which tried to 'exfiltrate' things during a build. Cutting off
internet access helped cut off these vectors of problems for the OS and
allowed interested parties to rebuild the OS from 'scratch' as needed. It
made things harder overall, but at the time was better than the alternative
of having a rebuild be drastically different from the first or 'other code'
added into the system without knowing why.

tl;dr: There is always a percentage of jerks out there who like to make
life miserable for everyone else. Removing the internet helps lower their
free ride.
