So company in HK is manufacturing and selling clones of Raspberry Pi -> so far about the closed source designs which prevent you from being copied 🙂
No matter if your design is OPEN or CLOSED this do not stop others to copy and clone your design, this is not rocket technology after all, if they have one of your boards they can de-solder all components, then strip the board layer by layer and copy it 1:1.
The real protection for Raspberry Pi was that Broadcom didn’t sell few years their chips to anyone else than the RPF, but with the recent announcement http://www.eetimes.com/document.asp?doc_id=1323198 Broadcom seems didn’t resist and start selling these chips to anyone with cash.
There is one more original design which I saw today again with Raspberry Pi based processor:
Board which run Linux but have no Ethernet connectivity and cost $30. To me at least seems that Raspberry Pi B+ for $5 more gives you +4 USB hosts and Ethernet to be a better deal. This probably try to compete with the recently announced Raspberry Module as have more sophisticated power supply.
There is an interesting discussion about this board on Raspberry Pi forum
