EDIT: Yeah, it seems like there are some far reaching not-understood legal implications of the "NC" license. Ok, we're going to re-commit and re-issue these with the BY-SA. Should be up in a few minutes.
I'm definitely not a lawyer and would like to hear from one interpreting the license for this use case, but it sounds like that could be interpreted to mean not okay to use for a business if it generated a commercial advantage, like HIPAA compliance.
Clarification from your lawyer (published on your site) would be good if you aren't okay switching to a more permissive license.
Suggestion: name them "FREE HIPAA DOCS AVAILABLE AT [URL]" and use a license requiring attribution, should make them hard to resell?
We removed the license restriction and changed it to CC BY-SA 4.0. Thank you for the feedback!
