In the business world, saddling yourself with higher support costs and lost productivity from lower-quality software would hardly be considered liberating. The quality issue is still relevant.
That should've been a wakeup call for free and open software advocates since at least 10 years ago..
So in a definitional sense they may be orthogonal issues, in a practical sense they most certainly are not.
Then, the question is whether a certain proprietary software as enough other qualities to make up for the missing quality of freedom.
Also, freedom is not a pure ethical quality. It means greater independence as well as freedom of action, which both can be very valuable (in dollars), for companies even more then for single users.
