Really not even remotely the same. The RPi is an exceptionally closed platform; in order to do anything with it you need to use Broadcom's binaries. Bear in mind that the main processor is actually the GPU; the processor that Linux treats as the CPU is in fact completely controlled by the graphics firmware.

To the best of my knowledge, that's untrue. It's a question that gets asked pretty frequently though, so if you know better than anyone else, you could do many people a favour by posting that information on the RPi forum.
In general, I think the RaspberryPi is a textbook example of where we don't want things to go if we want open systems under the user's control.
Personally I consider many of the foundation's public statements to be borderline fraudulent, and have a hard time with continuing to assume good faith given their behaviour and response to criticism thus far.
I recommend that nobody buy an RPi, for any purpose; it is an enemy of Free Software.
