Facebook is terrible:
The impacts of using a platform are not random; they are a direct outcome of that platform’s design decisions. Social media companies are constantly analyzing and fine-tuning their algorithms and adding new features. The features that facilitate a right-wing echo chamber on Facebook — such as how users connect with one another and how the algorithms work to maximize engagement — are intentional choices. Other platforms have chosen differently. Twitter chief executive Jack Dorsey has endorsed the importance of transparency in how its algorithms work and is considering enabling users to choose or even create “their own algorithms to rank the content” they see. Because the algorithms that decide what will be shown to users shape their news consumption in such a powerful way, this level of transparency could be an important step in promoting public trust in social media.
