Pshh...neither do I.
I love Diru with all my heart, but that doesn't mean I hate Sadie because they somehow look like them. I'm happy that Sadie wanted to have Diru for inspiration, there's nothing wrong about it.
There are a lot of bands that maybe "look the same" if you look only from the outside. Only when you get to know more about them, their music, then you can tell if they're really alike or not.
