I totally respect your position, but something tells me that Facebook is most likely doing their best "CYA". I certainly see how it appears on the surface that they are solely seeking to secure all the rights to material members place on their network, whether for present and future monetary gain. However, let's consider the fact that they were almost sued into oblivion early on by a party claiming that Facebook founder Mark Zuckerberg stole their idea for "Harvard Connect". I would expect that after that experience they exercise an abundance of caution in matters of legal concern. Further, failure to protect investors interests also creates exposure just as perilous. It's fair to say that their duty is to protect the interests of their investors first and foremost, then the interests of their members. A relaxed position towards control over their network and materials posted to it would arguably open them up to lawsuits well-beyond those they already probably see. So essentially they're damned if they do and damned if they don't.
