The 'free as in beer' vs 'free as in freedom' naming has always been a problem. Recently I started thinking about the word 'public' in place of 'free', as in 'public good'. Thoughts?
Only public domain is "free as in absolute freedom". Or as rms says:
“This is based on two essential freedoms: to make exact copies and to copy and distribute your modified versions as you wish.” Anything less “subjugates the user”.
The clearest I can come up with right now is "free as in liberty" vs. "free as in a gift to you".
