Free speech advocates worked diligently and successfully to overturn the portion relating to indecent, but not obscene, speech. They argued that speech protected under the First Amendment, such as printed novels or the use of the "seven dirty words", would suddenly become unlawful when posted online. Critics also claimed the bill would have a chilling effect on the availability of medical information. Online civil liberties organizations arranged protests against the bill, such as the Black World Wide Web protest, which encouraged webmasters to make their sites' backgrounds black for 48 hours after its passage, and the Electronic Frontier Foundation's Blue Ribbon Online Free Speech Campaign.
