By Dr. Hany Farid, professor and chair of the Computer Science Department at Dartmouth College and a senior adviser at the Counter Extremism Project. "Online platforms today are being used in deplorably diverse ways: recruiting and radicalizing terrorists, buying and selling illegal weapons and underage sex workers, cyberbullying and cyberstalking, revenge porn, theft of personal and financial data, propagating fake and hateful news, and much more. Technology companies have been and continue to be frustratingly slow in responding to these very real threats with very real consequences. Most notably, in the fight against online extremism, technology companies have been largely indifferent to the fact that their platforms are being used to recruit, radicalize, and glorify extremist violence. The public is, and will continue to grow, impatient with their intransigence and indifference to the harm that their technology is yielding. And the time is now for technology companies to get into it, and win it, by taking their social responsibility more seriously.”
