Guys, this is honestly pretty disappointing. The illustrations you allege "infringe" are, as many others have pointed out, extremely similar to prior work on The Noun Project. In fact, I recently used a "flat" newspaper image on a recent project that you'd probably call me out for "stealing" from you... which would be true, were it not for the fact I designed that asset almost two years ago. That basic newspaper graphic has existed for at least three years. It's almost generic at this stage.

The sad thing to me is that it seems as though you mistakenly believe you've created your visual style out of thin air, and are unable to recognise or admit you used other artists' work as inspiration.

Even worse, in fact, is that you made the conscious decision to promote your company's visual aesthetic as part of a "design movement". You essentially encouraged others to copy your "look". If you made it clear from the beginning that you felt ownership over your visual aesthetic, nobody would have considered it ethical to release a "LayerVault UI kit". However, you continually referred to your style as "flat design" and repeatedly suggested you wanted other designers to follow.

I find your actions pretty difficult to follow. Yes, some of their assets are similar, but how can you not recognise why issuing this DCMA leaves an extremely bad taste?
