How does using an ARM CPU go with the fact that Arduino is open source hardware (while Cortex M3 isn't) ?

I'm not sure Atmel AVR microcontrollers (used in the rest of the Arduino line) are open source hardware either. Sure, they are fully documented from the user's perspective, but Atmel doesn't give away source (Verilog/VHDL/etc.) for the core.
(I'll give you that ARM is more patent-encumbered.)
