Facebook's testimony before Congress started with a surprise as three protestors held up posters showing Mark Zuckerberg and Sheryl Sandberg as a two-headed octopus wrapped around the world

House of Representatives

• During the House Judiciary Committee's hearing on social media content filtering, three protestors held up signs during the testimony of Monika Bickert, Facebook's head of global policy management.
• The images appeared to depict Mark Zuckerberg, Facebook's CEO, and Sheryl Sandberg, Facebook's COO, as two heads on an octopus with its legs stretched around a globe.
• There is a URL at the bottom of the image - which appears to lead to the website belonging to a group called 'Freedom from Facebook.'

Shortly after Facebook's head of global policy Monika Bickert's testimony began at the House Judiciary Committee's hearing on social media content filtering, three protestors held up images behind her. 

The small posters appeared to depict Mark Zuckerberg, Facebook's CEO, and Sheryl Sandberg, Facebook's COO, as two heads on an octopus with its legs stretched around a globe.

The protestors silently held the images for a few seconds, which was available on the livestream of the event.

Chairman Bob Goodlatte then interrupted Bickert, and asked the protestors to stop - which they did, and then left the hearing. 

There was a URL at the bottom of the images the protestors held up, which appeared to led to www.freedomfromfb.com, a website owned by the group 'Freedom from Facebook,' which describes Facebook as a monopoly and urges site visitors to sign a petition asking the Federal Trade Commission to break it up.
