Yesterday, before I actually did my research and heard LV reply to this, I would've whole-heartedly agreed with you. However, it seems amazingly obvious that it's not even about the fact that it's Flat UI, but rather a blatant attempt to copy LV's assets. It cannot be a coincidence that they managed to magically get the same color palette, icons, and what not. As a designer who has had work stolen and have friends who have suffered from the same, I think we need to stop victimizing the author of the GitHub assets. LV sent them a friendly email which was the way to do it, they were being jerks about it (as I'm sure has happened to many of us), and they tried to play it off. So what? Shrug it off? Absolutely not. If you don't expose a thief, you're responsible for the next thing he steals. LV didn't even sue them, they merely said "Hey, we tried to tell you to take this down or at least change it the nice way, but you're acting like a criminal here. If that's the way you want it, I'm going to treat you like a criminal."
