I think you can see the DCU moving towards the chaos we've seen in Doomsday Clock pretty clearly now, particularly with Tom King's stuff where Batman's relationship with the GCPD has become strained, and the Sanctuary confessions getting leaked. I can see how the public's trust in superheroes would become dangerously shaken by all this once the Superman Theory gets leaked on top of all.
For 15 years, the general populace has mostly revered the superheroes of the DCU largely thanks to Superman being this beacon of hope that everyone could implicitly trust to never let them down. With the Sanctuary confessions showing how broken and flawed these costumed heroes are, plus the revelation that the US government may have been bankrolling not only them, but the super-villains that have caused so much destruction and murder for so many years, I can certainly see how that would unleash a lot of pent-up resentment.
In a way, it's a fitting allegory for the hope & optimism of Obama's America that swiftly became the fear and hatred of Trump's America today after a series of high profile leaks, and pent-up economic resentments blew up in everyone's faces.
