This is not the first protest of this kind on Wikipedia. On January 18, 2012, the English-language section of the knowledge clade was blocked in a similar way. So the website expressed disapproval of two bills discussed in the US Congress – Stop Online Piracy Act (SOPA) and Protect Intellectual Property Act (PIPA). They too were aimed at regulating free speech on the internet. And on October 4, 2011, the Wikipedia section in Italian – then in the Italian Parliament passed readings of a similar bill – DDL intercettazioni.
