Technology could erode the evidentiary value of video and audio so that we see them more like drawings or paintings — subjective takes on reality rather than factual records.

More than 250 Facebook employees have signed a letter protesting the company's policy allowing politicians to buy ads that make false statements, the New York Times' Mike Isaac reports.

Why it matters: As the 2020 election looms, critics fear the company's policies and security measures are insufficient to prevent a repeat of 2016 — when misinformation, some directed from overseas, ran rampant on the social network. Facebook's leadership has defended its policy as a protection of free speech in a democracy, even as politicians push the policy's boundaries to try to expose its flaws.
