REUTERS/Joshua RobertsIn the aftermath of last year's presidential election, tech execs were unanimous in denying that their various platforms had anything to do with the spread of falsehoods, fake news, and outright lies that allegedly contributed to President Trump's unexpected election. "Personally, I think the idea that fake news on Facebook, it's a very small amount of the content, influenced the election in any way is a pretty crazy idea," Facebook CEO Mark Zuckerberg said less than a week after the election. How wrong he was. Even after it was apparent that the spread of fake news did play a role in the outcome of the election, the tech world wasn't sure it could or should stop it.
