The thing about DMCA anticircumvention exemptions is that they don't last: they have to be constantly renewed, and the one you mention has in fact lapsed. Plus, they only get you out of the "anticircumvention" provisions, not regular old copyright law or the more familiar DMCA notice-and-takedown procedure. In other words an exemption may allow you to legally remove or break DRM or other copy protection, but it doesn't give you any rights to make copies or display works. As best I can tell, they seem to be operating on a "see what we can get away with" model, which appears to be working out pretty well for them.
