Mark Zuckerberg joins Mayer in hitting back at critics of tech companies, saying US government did ‘bad job’ of balancing people’s privacy and duty to protect.

Marissa Mayer, the CEO of Yahoo, and Mark Zuckerberg of Facebook struck back on Wednesday at critics who have charged tech companies with doing too little to fight off NSA surveillance. Mayer said executives faced jail if they revealed government secrets.

Yahoo and Facebook, along with other tech firms, are pushing for the right to be allowed to publish the number of requests they receive from the spy agency. Companies are forbidden by law to disclose how much data they provide.
