First of all, I just want to point out that the recent protests and other actions in relation to the issue of SOPA/PIPA (bolstered by varying degrees of blackouts on websites like Reddit, Wikipedia, and Google) quite likely amounted to the most politically active day in the history of the world -- in terms of people discussing legislation, issues of free speech, and governmental corruption. Furthermore, we are quite likely to see evermore people championing the cause of free speech (and challenging legal restrictions upon it through loopholes like copyright and trademark). These are very hopeful developments.
However, what I find particularly noteworthy is the kind of information that the government is looking to restrict... namely, access to art. On it's face, there are specious arguments about protecting artists and the profits of the movie and recording industry. These arguments have already been thoroughly dismantled by others -- in terms of artists thriving because of their works being spread and because artists created and thrived before any copyright laws existed. But the underlying issue isn't really about protecting artists -- or even corporatized industries profiting off of them. Rather, I feel, the issue is about the plain censorship of political dissent.
