I have often wondered if the Zeta's intentions are truly benevolent. And every time, I remember that malevolent aliens are already here, and have abused us for many centuries (Antarctica). Honestly, they have tech that we cannot understand at the present time. If they wanted to make a hostile takeover, I don't think we could stop them. So, I guess we all get to find out what they plan to do with us, one way or another. I like to think that Creator didn't bring us into existence, just to watch us fail and die.
