The reason I tend towards Elimnatus and TCTTS's versions is that the revelations will bring some uncomfortable questions/assumptions.
If they've been among us for years (since Roswell and probably before) it means a lot of things and I do not have enough faith in humanity to think that we could constructively integrate our new found place in the cosmos. As soon as it's made public, humanity has to immediately realize we are essentially powerless in our own homes, and that sort of subservience isn't going to sit well. The fact that they've been able to largely come and go without being hindered means a couple of life altering things immediately. We can "get got" at any moment because our tech is obviously eons behind alien tech. It also means everything about the way we live is subject to a reset, since clearly the aliens have some sort of essentially free energy. If they are hostile, they can wipe us out whenever they want (and why havent they already?) And if they're friendly, they've mastered energy in a way that makes everything about the way humanity operates obsolete.
Now...*that's* disruptive. Makes that Guthrie lady and Bucky ball and the Epstein files basically meaningless pretty quick.
