A protest for Anonymous (the people who wear Guy Fawkes masks) was held in front of Hotel de Ville (City Hall) yesterday. They were chanting and their signs seem to be talking about the attempt by many developed countries to censor the internet.
I have heard that the French will protest anything (a stereotype, I know), but this is something I actually agree with (not Anonymous as a whole, but stopping censorship of the internet).

These two bills are only in the US, but other countries are trying to make changes in this direction as well... including China and North Korea. Yay, censorship! It leads to great* things.
