The Google Code PDF link is about the 7th search result, so that's likely how this was found:
At my university I haven't seen anything this egregious, but students will use Google Code or GitHub for course projects, ignoring that they are public. I used BitBucket's free private hosting for a recent project, and GitHub is great about supporting students if they just ask.
I've read that they give out private repositories for school projects, but they haven't replied to a request I've opened 2 or 3 days ago. I got a paid account because I needed the repository today.
