It's dumb. It doesn't solve any problem with just one port. Also, there is no reason a project like this should be on KickStarter. It is a very simple item that requires virtually zero development. You could basically call up a Chinese manufacturer with a spcification and order them yourself. Order a small amount first if you don't have the capital, and they will almost guarantee to sell out, but larger volume with the proceeds. Make a tidy profit.
Develop an elegant and efficient dock/hub with 2 USB-A and 2 USB-C out the front, and 1 Ethernet, 1 mDP, and 1 USB-C for charging out the back - now that would be a solution that satisfies a need. Get it down to about the size of a Snicker bar, offer it in the Macbook's colors, and match Apple's $79 price, and you've got yourself a real winner.
Maybe have a couple of versions, for HDMI instead of mDP or something.
