AgereSystems/LSI develops Linux code for a chipset, when some major
buyer of their chips sponsors the developement. They are obligated to
make profit or at least break even on the Linux work. Within that
constraint, their staff has been as helpful as possible over the
years.
If their core Intellectual Property were Open Source, it would put
them at a competitive disadvantage.
