About the closest I can think of is the use of LGPL in software, where as
Free software can be distributed simply as a binary in a proprietary program.
Even then this is merely a compromise because the additional software isn't
Free.
The big issue is that the only distinction between proprietary and Free
software is the licence and the rules of distribution, beyond that there is
nothing else it can gain in terms of functionality.
Some have argued that 'closed/proprietary' software is needed in high risk
situations like banks, utilities services and security to keep it obscure
from attacks but that is a straw man argument. Security through obscurity is
not security at all.
