Did you try to go to Wikipedia on Wednesday? Maybe you noticed a big black bar in place of Google's logo yesterday? Those were moves against the proposed Stop Online Piracy Act (SOPA) and Protect IP Act (PIPA), which stars like Ashton Kutcher, B.o.B, Aziz Ansari are vocally protesting.

The two acts aim to prevent piracy, but in doing so, they also threaten to censor the Web. Supporters of the bill believe it's necessary to protect American intellectual property, while opponents believe that it infringes on Americans' freedom of speech and gives the government unmatched power over the Internet.

"Please don't ignore what's happening here," Ashton tweeted to his 9.2 million followers. "IMPORTANT MOMENT IN HISTORY! #StopSOPA."

B.o.B. also tweeted about the acts, including a link for Google's 'End Piracy, Not Liberty' petition. He wrote, "I'm not usually into politics but .... this has gone too far... we have to fight for our freedom ...."

"Think about it," he continued, "All the information we obtain and all the people we communicate with via Internet. This a blow to the heart of the American people who have been able to put food on the table from the opportunities provided by web."

Aziz, The Lonely Island, MGMT, OK Go and Trent Reznor of Nine Inch Nails also signed an open letter to Washington from artists and creators, which expressed their "serious concerns" regarding the two acts.
