"Cloudflare, a San Francisco content delivery network rumored to be prepping for a $3.5 billion IPO, is no stranger to controversy over its absolutist free-speech policies–and often embraces the debate. The latest flashpoint was a December Huffington Post article reporting that the company provides its web-traffic optimization and security protection to seven entities on the U.S. State Department’s list of foreign terrorist organizations–including al-Shabab, the al-Aqsa Martyrs Brigade, and Hamas. U.S. law forbids providing 'material support or resources' to these groups. But something has changed. The Counter Extremism Project (CEP), a nonprofit that tracks such groups, has alerted Fast Company that at least three sites mentioned in the Huffington Post article no longer use Cloudflare: Hamas (Hamas.ps), the Popular Front for the Liberation of Palestine (pflp.ps), and the English-language Taliban site (alemarah-english.com). 'I’m curious as to the reasoning for that,' says CEP content review specialist Joshua Fisher-Birch, who noticed the changes. His curiosity might not be satisfied: His group has sent several letters to Cloudlflare over the past two years, alerting it to some of these organizations, as well as others, such as the white supremacist Nordic Resistance Movement, using the company’s web services, but has not received any reply from Cloudflare."
