I think it’s a little much to expect people to always qualify ‘Free as in beer’ anytime they ever use the word free in a monetary sense in a Linux community.
That seems really odd to me. I don’t expect people to qualify use of the word free in a montery sense in a Linux community, I expect people to avoid using the word free in a monetary sense entirely. And it doesn’t seem a little much, it seems blindingly obvious if one’s goal is to communicate effectively.
