Oh my god, it is you who is confused.

'Free' in free software is used in the sense of *free speech*. You are
confusing it with *free beer*.
I did not bring the License issue in to this discussion.
Then you haven't discussed at all! Free software is all about freedom and
hence license does [in fact only thing that] matter. Money doesn't matter.
Free software can also be paid/charged.
Any thoughts in favour or otherwise?
All free software are open source software because publishing source code is
essential to freedoms required to be a 'free software'. Not all open source
software are free software. (See my next mail in reply to vijay in this
thread to know why)
These are the freedoms that any license should grant you for it to qualify
as free software:
- Freedom 0: The freedom to run the program for any purpose.
- Freedom 1: The freedom to study how the program works, and change it to
make it do what you wish.
- Freedom 2: The freedom to redistribute copies so you can help your
- Freedom 3: The freedom to improve the program, and release your
improvements (and modified versions in general) to the public, so that the
whole community benefits.
@Balaji: Hope this clears your doubt.
