I must admit it looks oddly similar. We did not see it on Coda site before using it. Not sure of the provenance (I will ask my designer).
As smackfu noted, the water drops are not exactly the same. But obviously, since it's very similar, we'll change it. It's very accidental and far from intentionnal.
I understand, and it's reassuring that you were not aware of it.
However, it's not "oddly similar." Yes, it's been rotated, mirrored, and slightly modified, but it's their icon and somebody blatantly stole it and tried to pass it off as their own work.
Interestingly, it actually happens so frequently with Panic's work that they have a page dedicated to people ripping off their icons: http://panic.com/extras/ripoff/
