There's so many examples of crowd funding doing this, its really sad.
Facebook is covered with ads for this sort of thing too. One example I complained about was an electric screwdriver where literally the only difference it had to existing products on the market was they changed the microUSB port to USB-C. The response from the people doing it was "its out first product so we wanted to start out small".
I guess there is nothing to stop these "companies" creating clones like this, they likely buy from the existing manufacturer and just make minor tweaks. But it still seems scum-bag move to me, especially as they can cut and run with the money if they feel like it as there are no guarantees on crowd funding.
I backed a handheld printer that can print on your hand, sounded a fun thing for a convention I was attending. They never delivered but an identical product turned up on Aliexpress. Made me very wary of crowd funding.
