This is the model that social media had. Facebook, Twitter, Instagram... they all started of just showing you content from people your followed. Or course they now all demand to show you "recommended" content and with that take on the responsibly of how "pleasant" that recommended content is. Where did they do this? I bet few people truly know. My personal guess it's because injected ads and promoted content logged to out of place between your friends posts whereas there is little difference between ads and most popular posts.
