Arduino is an example of open hardware. You can't sell a branded Arduino clone, but you are perfectly entitled take the schematic, build a clone board and sell it for peanuts. Fake FTDI is more of a problem because of the recent debacle where the drivers wouldn't work with counterfeit chips.
I've often had Sparkfun boards fabbed via Oshpark, rather than buy and pay for expensive shipping from the States.
