Google, Facebook, and Amazon are all massive online platforms built on serving everyone. But recently the companies have come under fire from both the far right and the far left for how they moderate public discourse.

In recent months, these tech companies have started policing content more. While that has angered some on the right, others on the left felt that the platforms were too slow to react. That's posed the question of what side do these businesses take and whether it's beneficial or harmful to society.

Following the violence in Charlottesville, Virginia, tech giants like Twitter, Facebook, and Apple began clamping down on Neo-Nazi groups. Facebook shut down eight group pages that it said violated the website's hate-speech policies. But there was still frustration that the social network didn't remove the event page for the white supremacist rally until right before it happened, Axios reported.

Separately, the right has expressed concern that progressive-leaning companies won't give their views a platform. The party opposed Google's firing of James Damore, the engineer whose internal memo on women at tech companies sparked controversy in Silicon Valley. This side believes companies like Google or YouTube have the ability to silence their opinions.

Meanwhile, the left is still worried that fake news impacted the election. Facebook and other platforms are still wrapped in investigations into Russia's involvement in the 2016 campaign. What's more, Senator Mark Warner of Virginia, a top senate intelligence committee Democrat, has reportedly spoken about fake news with Facebook employees several times this year, a source told Axios.
