WE’RE HEARING THIS FROM A LOT OF QUARTERS: The Tech Giants Must Be Reined In: Silicon Valley usurped the role of traditional news media, without assuming any accompanying social responsibilities.

This fall, Facebook, Google and Twitter executives were hauled before a Congressional committee after being asked to investigate allegations of Russian meddling. Facebook admitted that 126 million of their users may have seen content produced and circulated anonymously by Russian operatives. Twitter admitted to working with 2,752 Russian accounts, and that 36,000 Russian bots tweeted 1.4 million times during the election. Google testified that 1,108 videos with 43 hours of content related to the Russian effort were uploaded on YouTube, and that Russians placed $4,700 worth of search and display ads on its network.

But this is only the tip of the iceberg in terms of the kind of meddling the social media giants tolerated. And getting a grip on how to address these issues will be no small feat. The social media business model itself is flawed and unethical; the tech giants have usurped the role of traditional news media—without assuming any historic social responsibilities.

Silicon Valley’s image has really taken a hit.
