This is part of the Free Software as Lego Article.

    This view precludes the free-of-charge aspect of free software,
    but that is the easiest to grasp,

Actually, this is not an aspect of free software at all.  "Free"
refers to freedom, not price--free software does NOT mean
"free-of-charge".  So this is not an omission; it is correct.
Please don't say it is an omission.

    Note that this article is really about "Free Software" not "Open
    Source". I can't see any additions Open Source gives to Free
    Software, only jargon and limitations...

I agree with what this says, but I think this paragraph 
does not really fit into the article.  It would be better
to "do" it rather than "say" it.  In other words, you could
simply write about "free software" and not mention "open source".
