Some people because just because you're different--on Earth, alien, literally. We don't get many non-Terrans. And our sun gives you all those powers. As many people as see you three in action, see all the good you do, there are those who fear that. Some out there can't believe you wouldn't use it to dominate the planet--because it's what they would do. Or else they're just insanely paranoid and-or prejudiced.

And... Superman was one the first superheroes we saw. [She smiles softly.] He can't stop himself from helping and protecting the innocent, and his ethics aren't for sale. It puts him squarely in the way of what some particularly nasty types want--people like Luthor. Then, too, criminals and the larger supervillains end up carrying grudges because he stopped them from hurting others.

So they want to hurt him. And because people like to generalize, and because all three of you keep helping, you're in the cross-hairs too.
