There is intelligence but it aint here. I'm a firm believer that they are watching us but only for the entertainment just like we watch TV.
They dont care how it ends so they dont manipulate events here.
If they did have a hand in the initial failure of our Hubble Telescope it was because we were about to see something we shouldn't. That small correctable error might have provided them additional time to complete their safeguards.
They dont dare reveal themselves because we cant handle the truth. Besides, Our ignorance is what make us entertaining to them.
