What's best for you? We think the third view is the most realistic and enlightened. Of course, this also depends on any agreements you may have made or releases that you signed. We think the Crimson should either re-think its position or begin using releases if they wish to prevent their subject from reproducing the contents of an interview. Would you improve your position by transcribing the interview and only reproducing your responses? Perhaps, but you can certainly make a good fair use argument for including the questions.
What about the DMCA? The Crimson may also bypass all this and seek to use the DMCA to remove the recording from your site. We think that would be a mistake and not just if they fail to consider the fair use ramifications. It certainly would not fit with the spirit of transparency and freedom of information that the newspaper seems to support. (Like, what would Larry say about all this?)
