Government contracted construction workers: We Have No Idea Where Your Tax Money Goes
When tasked with answering the simple question "Which specific bricks did my tax money buy this year", the two veteran construction workers looked confused and tried to explain that that's not really how taxes work.

I'm not sure the analogy fits 100%, but it's the closest I could think of. This reads like the author thinks the Facebook algorithm is a human-readable decision tree that only takes into account the data of a single user at a time.
As usual, the problem is not data "collection" or "retention" or "privacy", but "creation". Regulation will always remain woefully inadequate to control such organizations, and the only solution is to adopt systems that don't spew user data everywhere in the first place.
