It’s not about the lenght of the list, but about the teleology of the action. Recently from Audrey Waters:

An algorithmic timeline . . . (is) a “solution” for “engagement” and for “growth” — a response to the demands of investors and shareholders, not the demands of active users.

Algorithms are not neutral, although they are frequently invoked as such. They reflect the values and interests of their engineers, although it’s hard to scrutinize what exactly these values and interests entail as the inputs and calculations that feed algorithms are almost always “black boxed.”
