Usage Note - Nonprofit or Non-Profit?

 The AP Stylebook has Nonprofit while this site has some comments on which:

[T}he people at AskOxford, an email interface for addressing the OED, noted the use of the hyphen in the OED as a traditional respect for the term as originally developed, while the “new” American version has more quickly accepted the term as nonprofit.

Technically, however, there seems to be a rather clear and definite solution. Grammarians would likely argue that use of the term in it’s hyphenated form indicates its placement as an adjective, describing a following noun. For example, the non-profit business model is growing in its popularity. In its unhyphenated form, the term is used as a noun. Together, they could be used as follows: the non-profit business model is used as a foundation for many of the nonprofits across the globe.

But do you trust a site about grammar with an " it's " signifying possessive?  Hmmm ...
