Rather than fight you Ben, I decided on instead focusing on our different viewpoints.
If Open Firmware is proprietory, then so is: PCI, AGP, USB, Firewire, AC97
As they all obey the same rules as open firmware: establish a standard that allows any company to make their product able to work within the standard.
In fact, that is what defines a standard.
But, if you'd like a clarification that will halt this arguement:
SmartFirmware is a proprietory piece of software on the Pegasos motherboard that follows the Open Firmware standard, enabling it to configure the system, add expantion cards and even boot up OS's in accordance with the Open Firmware specification and is guaranteed by the Open Firmware standards group.
uBoot is an open source piece of software on the AmigaONE motherboard that has no standards body behind it, thereby not guaranteeing it to work with any product, peripheral card, expantion port nor even an OS thereby making the implimentation on the AmigaONE proprietory to the AmigaONE.
Unless, of course, Hyperion is willing to guarantee uBoot will do the same things Open Firmware's trade association does, namely state that any firmware that follows the defined spec will work exactly how the spec details. If you'd like to set up a trade association for uBoot, a friend of mine does this for a living and I'd be more than happy to pass along his contact information to you.
In the end, as with all things, it depends on your point of view. I view things in terms of how they communicate. Now, I might be wrong here, but you appear to view them in terms of ownership. Neither viewpoint is invalid, but they don't see eye to eye either.
