re: SOPA: 5 Key Provisions Of Anti-Piracy Bill
The last such law, I think it was the DMCA, passed in the Clinton administration, had the same justification. The official who herded the bill through eventually renounced it saying that it didn't serve the purpose and was used precisely to protect outdated and dysfunctional business models and practices. The last time it was US companies were able to fill the digital music gap. This time, the more global and comprehensive nature of the law will end up leaving the field to foreign companies and cost the economy billions, if not trillions. It will encourage protectionism in foreign countries by giving them an excuse to "protect" their people from US corporate whatevers.
The worst part of the bill is the failure to demand a quid pro quo from the corporate beneficiaries of the law. For example, drug companies should not be allowed to charge US consumers a price multiple for the same drug that they sell in other developed companies. There need to be provisions for competitiveness and new technology. One person's pirate is another persons competitor. SOPA is store bought legislation that benefits a very limited subset of the population and could likely hurt the economy. We need to protect IP as a precious national resource, it's just that SOPA isn't the way to do it.
