Turns out Wikipedia is suddenly actually like a super death note, where the page edit actually causes the event to happen the next day.

Billionaires hire staff to keep their death date from being published. Politicians assassinate their rivals by adding a cause of death to their wiki. Insurance companies suddenly have to monitor for publishing of freak outbreaks of fire in customers insured buildings.

Meanwhile, the shadow government keeps trying to publish the "Wikipedia ceased being a causal event source on..." section to disable the behaviour, but it keeps getting reverted by Wikipedia itself.
