The Electronic Frontier Foundation also weighed in, issuing a statement. "These heinous attacks must not be used to justify further erosion of our security, civil liberties or privacy," wrote EFF executive director Cindy Cohn. The privacy advocacy organization points out that there has been no public confirmation that the terrorists used end-to-end encryption, nor that it was the encryption of communications that caused the intelligence agencies to fail to detect the plot.
"What we do know is that strong encryption is crucial to allow political organizers, government officials and ordinary people around the world to protect their security, privacy and safety from criminals and terrorists alike. Any 'back door' into our communications will inevitably (and perhaps primarily) be used for illegal and repressive purposes rather than lawful ones," wrote Cohn.
