They don't care about design. If they did they would have created something original. Or at least they would have more than one source of inspiration to pick from. If they wanted to take the whole shape of OSX applications, at least they should have picked a different color theme. Here they stole the functionalities, the shapes, the colors and the metal textures that Apple's designers chose. eOS is designed by Apple, there's no one who care about design in the eOS team, at least not for the apps shown in the video. They're receiving bad critics because thieves receive bad critics. Hopefully they'll learn and their next version will have its own identity.
