Free Libre Open Source - isn't the same as free of charge !
Free Libre Open Source isn't the same as free-of-charge ! Free Libre Open Source is much more about the ethics and even politics of "freedom" !

The Open Source paradigm is producing very high quality code and Open Source companies (and increasingly, traditionally closed source ones) are providing real value to clients with this code.
What’s really driving the adoption of open source software is "freedom" ... open standards, a lack of usage restrictions, and not being locked into a single software vendor as their primary reasons for looking at or adopting open source solutions ... the ability to customize these packages to specific business uses - especially in vertical markets.
Freedom is key.
