That's ridiculous. Look up the meaning of "civil war." It does not include theft from third parties.
Again you must not have studied your history too well, or understand the dynamics of the situation in Somalia.
In the American Revolution, the Continental congress issued Letters of Marque to have privateers sieze merchant ships and provide arms, and supplies to the continental army and insurgent revolutionaries. The French specifically had a pass from these privateers because they were funding, and supplying our revolt. The English(our enemies) along with the Dutch, Hessian, and several other nation's ships were all fair game(and coincidently all happened to be French rivals economically or militarily).
The issuing of Letters of Marque continued even after the Revolutionary War as the US needed to increase it's force projection into the oceans immediately, and was incapable of fielding a proper navy. It wasn't until the US became a contender on the seas that Letters of Marque stopped being issued. Furthermore, any sailors caught by the British who came from these privateering vessels were not accorded POW status, but rather criminals of the high seas, and were enprisoned seperately with the high expectation that they were to be hanged.
Simply put, we robbed third parties during our revolution and even after our establishment as a nation. There was a reason that the British empire during the 19th century referred to Americans as brigands, theives and scoundrels.
In the case of Somalia, the money gained from Piracy is not the end all of the game being played over there. Certainly the ransoms are useful, and the pirates and towns rising up around those pirates are doing well, but the Islamic government currently in "control"(I say that loosely) is deliberately allowing and even secretly encouraging pirate activity in order to garner international attention. If anything it allows the Islamic Courts Union to highlight the weakness of the UN appointed Transitional government, which in turn grants legitimacy, and possibly funding and negotiations between the UN and the ICU. A prime example of this are reports of pirates docking in the Southern portions of Somalia where the Al-Shabaab "The Youth" permit their presence.
What's even more fun, is that there are also links between the the current Transitional UN appointed government and the pirates. The earlier Fox news link had one such example pointing out that Abdullahi Yusuf Ahmed of the provisional government might be trying to use piracy in conjunction with fabricated "thefts" to make Somalia a more central part of the War on Terror (which in turn would lead to more funding and military backing to the UN appointed government).
So you see piracy, in Somalia anyways, is a very integral part of the civil war that is occuring over there. Is it black mail to the rest of the world? Certainly. Is it pulling in "innocent" third parties, most definitely. But then, isn't that similar to the bargain we struck with France during the American revolution. France had a vested interest in seeing the colonies break away from Britain, and in return we privateered against France's military and economic rivals and had some cushy trade relations with them in the years following, including the Louisiana purchase.
