How does the Digital Millennium Copyright Act threaten freedom of expression? “The DMCA gives corporations the power to essentially purge from the Internet what they deem to be copyright and trademark violations, usually by forcing Internet service providers to remove offending Web sites. The act encourages such behavior because the law states that ISPs and Web host companies can avoid liability only if they comply with copyright owners’ demands to quickly remove so-called infringing materials. Search engines are also liable under the law for simply pointing users to Web sites, though they too can avoid lawsuits if they cave to the demands of overzealous copyright owners by removing certain search results. Intellectual property owners can simply make your voice disappear if they do not like what you have to say about them—whether you are liberal, conservative or neither. This is something that was much more difficult in a non-digital world.”
