On the Record: Andrew 'Boz' Bosworth, Facebook's hardware boss bbc.com

Recently Facebook found itself in yet another privacy storm – this time over its undisclosed use of human contractors to listen to and review audio clips captured through Facebook Messenger and – as we learned this week – the firm's Portal video chat devices.

Facebook "paused" the practice.

But now the team behind Portal – led by Andrew Bosworth – has launched a new range, including one that attaches to your TV. As part of that announcement, we learned that human contractors would be unpaused, and would be used once again to transcribe and analyse a small number of audio clips captured by the device.
