As a thought experiment, it's funny to think about what GPL enforcement could have done with SOPA, had it passed. Especially if software/firmware updates were distributed via the web.
On the one hand Sony is pushing for SOPA, but on the other hand Sony is violating the GPL. They could end up actively pushing through legislation that ends up significantly harming their bottom line.
I'm confident that regardless of the ultimate outcome of the Battle For Freedom on Internet and Intellectual Property, it will remain that the most wealthy most often gains financially from their own wrongdoings. The judiciary system will remain the warhammer of giants, way to heavy financially for most individuals and small companies.
