When we talk about "The Algorithm" in terms of social media, the term has just about taken on a meaning opposite to the original one.

My coder's view of the simplest possible algorithm: "People that I follow, their posts, ordered by most recent first." it's transparent, easy to understand, consistent, and a few lines of code.

Big Social media's "The Algorithm" : a complex, utterly opaque, personally targeted, frequently shifting internal set of rules that they manipulate to maximise engagement and revenue, while hiding this from the users whole attention is being monetised, designed according to business priorities.

Clearly, if you use the second kind of Algorithm then you are no longer an impartial common carrier.
