December 8, 2010 Hackers Give Web Companies a Test of Free Speech By ASHLEE VANCE <http://topics.nytimes.com/top/reference/timestopics/people/v/ashlee_vance/in...> and MIGUEL HELFT <http://topics.nytimes.com/top/reference/timestopics/people/h/miguel_helft/in...> A hacking free-for-all has exploded on the Web, and Facebook <http://topics.nytimes.com/top/news/business/companies/facebook_inc/index.htm...> and Twitter <http://topics.nytimes.com/top/news/business/companies/twitter/index.html?inl...> are stuck in the middle. On Wednesday, anonymous hackers took aim at companies perceived to have harmed WikiLeaks <http://topics.nytimes.com/top/reference/timestopics/organizations/w/wikileak...> after its release of a flood of confidential diplomatic documents. MasterCard <http://topics.nytimes.com/top/news/business/companies/mastercard-inc/index.h...>, Visa <http://topics.nytimes.com/top/news/business/companies/visa_inc/index.html?in...> and PayPal, which had cut off people's ability to donate money to WikiLeaks, were hit by attacks that tried to block access to the companies' Web sites and services. To organize their efforts, the hackers have turned to sites like Facebook and Twitter. That has drawn these Web giants into the fray and created a precarious situation for them. Both Facebook and Twitter --- but particularly Twitter --- have received praise in recent years as outlets for free speech. Governments trying to control the flow of information have found it difficult to block people from voicing their concerns or setting up meetings through the sites. At the same time, both Facebook and Twitter have corporate aspirations that hinge on their ability to serve as ad platforms for other companies. This leaves them with tough public relations and business decisions around how they should handle situations as politically charged as the WikiLeaks developments. Some internet experts say the situation highlights the complexities of free speech issues on the Internet, as grassroots Web companies evolve and take central control over what their users can make public. Clay Shirky, who studies the Internet and teaches at New York University <http://topics.nytimes.com/top/reference/timestopics/organizations/n/new_york...>, said that although the Web is the new public sphere, it is actually "a corporate sphere that tolerates public speech." Marcia Hofmann, a lawyer at the Electronic Frontier Foundation, said, "Any Internet user who cares about free speech or has a controversial or unpopular message should be concerned about the fact that intermediaries might not let them express it." She added, "Your free speech rights are only as strong as the weakest intermediary." [...] Continua qui: http://www.nytimes.com/2010/12/09/technology/09net.html
