From the film, Apocalypse must have at least some ability to read minds and influence them - how else would he have known to take Magneto to Auschwitz? Actually, there is someone who comes to mind with very similar mental powers: Sybok! From Star Trek... you remember. I grumble about it, but there is barely enough to the argument that Magneto was mentally manipulated, and a voiceover saying how he aided in the defeat of Apocalypse, that it isn't unrealistic for the major powers in the world to look the other way from what happened without screaming for Eric's head. But the Magneto villain well has finally run dry: make him a bad guy again and it will completely discredit Xavier, which is the last thing Fox should do. Since he didn't die, I really think he should fade away. Although it is foreign to the X-men movie universe, and duplicative of CA: Civil War, there has to be some governmental oversight to the X-men in the future films, right? I don't see how the X-men can just go about and do whatever they please, especially after what happened in Apocalypse. In the OT, the X-men were a secret force that only fully-emerged at Liberty Island. The government kinda strikes back in X2, and in X3 there is explicit mutant participation in the national security state (but still no regulation of the X-men themselves). In the new timeline, the power of mutants has been seen and heard by the entire world - literally - and it would be patently unrealistic for things to be unchanged in the future. Of course they could ignore it and do as they did in the past, but that would be a real disappointment.
