Properly speaking, "commercial" is an orthogonal concern to "Open Source" -- if software is sold by a merchant under a license, that license is commercial, whether or not the license is also an Open Source license.

You seem to want to create a new use of "commercial" where it on a continuum with "Open Source" but not merely the negation of "Open Source", such that there would be "Commercial" and then some poorly specified "gray area" and then "Open Source". I'm not sure that this is either a particularly good use of the term "commercial", nor a particularly useful concept regardless of the terminology. Non-Open Source or non-Free licenses always permit you to do something with the software (that's why they are "licenses").
