There are basically 2 overarching themes in the nu-Deus Exes that go unexplored - the control of media (especially news media)
there is no way this will ever get addressed
It's already been explored.
First in HR, when you break into the headquarters of news giant Picus and find news footage in the process of being faked to control the narrative, as well as learning that the news anchor Eliza Cassan who you been seeing on screens everywhere in the world is actually an Illuminati AI constructed to control people's reactions.
Throughout the game, Picus turns opinion against Sarif Industries (which they don't control) while painting Tai Yong Medical and Humanity Front in a good light (organizations they do control).
Late in the game, a Picus broadcast urges augmented to replace their "faulty" biochips with new ones that the Illuminati can selectively turn off to control augmented people. The attentive player will ignore the recall since it's already been revealed that the news is controlled by the enemy, leading to a humorous scene where Zhao is unable to shut down your augmentations for the Namir boss battle.
And then in MD, Picus is pushing the Human Restoration Act throughout the whole game - a UN resolution intended to complete the Illuminati's scheme to control augmented people that they failed to pull off in the last game.
You also have the Samizdat side mission, where you break into a bank vault to find proof that Picus faked the cause of a plane crash (claiming a crazed augmented man broke into the cockpit) to hide the existence of the secret military base that brought down the plane. You can upload the proof onto huge advertisment screens, but it obviously won't change anything.
Both because Picus is powerful enough to spin it as fake news, but also because the Illuminati is still secret in 2052. Jensen will never be able to convince the world that Picus is owned by a secret society that use the news to control the world, because that would contradict the events of the original Deus Ex.
