commitment to encryption and that Facebook has launched end-to-end encryption for Messenger. Both of these announcements came before news broke that Yahoo! has been running a government-requested e-mail scanning program for US intelligence interests since last year. The Yahoo! news will surely increase support for – and lead to calls for more systems like – Apple and Facebook’s encryption efforts. This is a pity, because these efforts really do little to improve cybersecurity. Indeed, they are arguably little more than security theater, distracting and taking resources away from addressing more substantive cybersecurity concerns.
