What isn't discussed much is incentives. Currently, it doesn't seem that aliens are acting in a way that would be consistent with their incentives. If they are powerful enough to get around the galaxy, they'd definitely be safe with closer encounters with us. Nothing we could do about it even if we didn't like it. I also imagine they would be bonded by morality similar to the way humans are and want to help us and the planet generally if they knew we existed. (More bellicose civilizations are less likely to achieve interplanetary travel before they blow themselves up.)
