[Disclosure: I&#x27;m an ex-FB employee.]<p>This is a bit of a click-bait title, and is somewhat true -- but not in the way you think.<p>When FB was developing hashtags and content features, there was a concern that it is tough to find a middle-ground between 100% purely algorithmic generated content (i.e. leverage tastes data and supply articles suited to your interests) and 100% curated content (i.e. leverage tastes data, but only show articles from &quot;reputable&quot; sources and&#x2F;or highly rated content, over shitty blog posts from amateurs.) The latter tends to do really well for engagement, as users can trust that the content they&#x27;re seeing is reputable and popular. However the big concern that a number of us were raising was that tech companies have employees that are very biased in ways that they cannot control: they&#x27;re younger, more liberal, and somewhat higher income, than the average FB user.<p>In my time there, I never heard of _explicit_ suppression of any viewpoints - with the exception of recent disagreements around the &quot;Black Lives Matter&quot; protests,  the first time that I encountered a situation where disagreeing meant you were labelled a &quot;racist&quot; - but I can see why well-intentioned product and policy decisions led FB content down this hole.
