I think it's not an indication that the government thinks the RIAA's problems are homeland security concerns, and would prefer not to be baited into discussing anything else I think about it.

The C in ICE is Customs, which has been charged with stopping counterfeit goods produced abroad from entering the USA, such as knockoff Rolex watches and Prada Handbags. Counterfeit goods have been charged with "reducing the desire" to own original goods, much like pirated music has been charged with reducing the desire to actually buy the CD.

If anything, ICE is probably the only department that administratively is capable of combatting piracy, since they have been doing it for so long under their own banner. They now get to do it under the Homeland Security banner.
