Current Noospheric models infer that SCP-570 has coalesced in such a way that total extrication of the anomaly from the Noosphere would result in the conceptual annihilation of the concept of soft drinks; due to both companies' status as members of the Global Occult Coalition's Council of 108, this course of action has been deemed unfavorable.
Okay, upvoted already. Gonna keep reading, but I love noospheric stuff and the companies being a part of the GOC is both fantastic and, unfortunately, surprisingly realistic.
EDIT: The sheer escalation is absolutely wonderful. The above is how we start. We end with the Scarlet King being tied to Coca-Cola, and, I might be wrong about this, did the Foundation release the Devourer in order to appease two megacorporations? It's… a lot of fun lol.
