A new podcast from the Electronic Frontier Foundation: The digital world isn't just a place you visit on your phone. It's the battleground where tomorrow's civil liberties will be won—or lost. Each episode of the EFFector podcast will fill you in on the most important news in digital rights, highlighting key developments in the fight for a world where technology supports freedom, not tyranny. We've all had the unsettling experience of seeing an ad online that reveals just how much advertisers know about our lives. You're right to be disturbed. Those very same online ad systems have been used by the government to warrantlessly track peoples' locations, new reporting has confirmed. In this clip from EFFector, we're talking about how advertising surveillance enables government surveillance. Subscribe to EFFector wherever you get your podcasts.
