Perhaps it depends on intent. Clearly, the creators of the content, and those who posted the content, did so for the sole intention of making it public and usable outside the LinkedIn system. Their posting of it on LinkedIn is incidental; what site is used or who owns it is largely irrelevant to them, whereas such things clearly do matter to any company or person creating and posting their own unique content to their own site.

At one point, to fight scraping, Craigslist changed their terms so that users assigned them copyright of listings rather than just a license. It didn't work well for them, but it's an interesting approach.
