The program explicitly passes control of the virtual processor to the
library for a while, and does not resume execution until the library
returns. References (usually many references) to specific exports
from the library are embedded in the program.
Operations over an asynchronous medium -- like TCP or PCI -- are quite
different. The GPL, for example, is very specific about its reach.

Do you then agree that boot loaders depend on the BIOS, and since
Debian does not include free BIOS software, we must remove boot
loaders (and subsequently everything that depends on them) from
Debian? We certainly cannot execute much in main without a BIOS, but
we do not find a BIOS in main.
At the least, do you agree that packages which implement only one end
of a protocol must be moved to contrib if nothing in main implements
the other end of that protocol? For a partial list, see "mass bug
filing for unmet dependencies."
