That makes no difference: while I am not a layer and you absolutely should contact your lawyer before doing something like this to get your ducks in a row (and generally you would thereby be a fool to use what I say as "legal advice"), the relevant fair use here comes from legal precedent and even explicit exemptions required to ensure "software interoperability", not some concept surrounding "non-commercial use" (which I think is highly unlikely to protect you in almost any situation).
