It's obviously stupid to actually believe that, information doesn't "want" anything. What it actually means is that information tends to gravitate towards wide dissemination. It's commenting on the inevitability for information to become public. We can put effort in to try and stop that, but it's ultimately futile.

Pointing out the flaws of DRM schemes with "information wants to be free" doesn't mean that you necessarily think information should be free, merely that it's the natural state of things.
