As Facebook-owned Instagram celebrated reaching 500 million monthly users, CEO Mark Zuckerberg posted a photo of himself celebrating the occasion.  However, sharp observers noticed that the laptop on his desk which has a webcam, was wrapped around with tape.  Additionally, there also seems to be an obstruction on his mic jack. 

A report by The Telegraph points out that Zuckerberg covering up will strike many as ironic considering the long-held beliefs of some that Facebook is doing its utmost to eavesdrop on its users. 

In the past, Edward Snowden ran a program called "Optic Nerve" which used Yahoo web chats to capture images from millions of accounts.  James Comey, the director of the FBI, had also revealed that he tapes over his webcam earlier this year. 

The report points out that recently, Facebook was forced to deny claims that it is using smartphone microphones to listen to phone calls in order to better target adverts.
