The criteria for allowing a source are not objective — and how could they be, when all sources are more or less bad? I understand that on the same story you will allow sheer propaganda from the BBC, but don&#x27;t allow a factual report from <i>The Intercept</i>. The latter is unlikely to be a comfortable read, and may lead to some users quitting.<p>But don&#x27;t pretend there is some objective measure of &quot;unbiased&quot; that for example The Guardian or BBC pass and other outlets don&#x27;t. That is the same mindset any gatekeeper has: to bring the best news to the readers, where &quot;best&quot; is of course subjective. Be it with an algorithm or directly, Facebook editorializes — heavily, it would appear.
