Every platform ultimately makes choices in how users engage with it, whether that goal is to drive up engagement, ad revenues or whatever metric is relevant to them. My general read is that Facebook tries to message that they're "neutral" arbiters and passive observers of whatever happens on their platform. But they aren't, certainly not in effect, and possibly in intent either. To preserve existing algorithms is not…
It's pretty laughable for Facebook to claim they're neutral when they performed and published[1] research about how tweaking their algorithm can affect the mood of their users. [1] https://www.theatlantic.com/technology/archive/2014/06/every...
There's something of an analogue to the observer effect: that the mere observation of a phenomenon changes the phenomenon.
Facebook can be viewed as an instrument for observing the world around us. But it is one that, through being used by millions of people and personalizing/ranking/filtering/aggregating, affects change on the world.
Or to be a little more precise, it structures the way that its users affect the world. Which is something of a distinction without much difference, consequentially.
