How GDPR protects your social media data (even if you accept all cookies)

Why are apps and websites increasingly asking us if we're willing to share our cookies?

The EU's General Data Protection Regulation may be somewhat annoying to the average consumer, but for social media companies it was a wakeup call about the huge amount of private data they'd accumulated, says Facebook whistleblower Frances Haugen.

And that's a slippery slope for the likes of Facebook or Google.

"One of the things that you get as part of GDPR is the right to request any data that a company has on you," Haugen tells Ian Bremmer on GZERO World.

For companies, she says, they were suddenly being asked to disclose just how much stuff they had on you.
