SOPA & PIPA are the sort of Bullshit censorship models we can do without on the internet. That’s why I went dark on the 18th January and thankfully they were defeated this time. Have a read of some background to the well thought out arguments as why we need to oppose these types of measures now and most likely in the future too is easy to find.
Just because SOPA and PIPA have been shelved doesn’t mean that we don’t need to remain vigilant. ACTA is the prime example right now… this is a global treaty that likely has a greater chance of being passed in various countries. Also keep in mind that SOPA text can be amended to other legislation, much of which isn’t even read completely.
