The linked license is from a version that's over a year old (April 2008). Who knows what the terms were before that. Though, if there weren't any explicit terms, that means that distribution was prohibited.
Now, the most recent version (10.5) that was posted a few days ago is licensed under the Apple Public Source License... which expressly allows commercial use. But from my initial reading it is like the GPL, in that it's a viral license. Since this boot loader is based on Apple's boot loader, it must also be under APSL.
There is also a note in a README that says for commercial purposes contact the authors, but since this is APSL anyway, I doubt that they have the ability to grant a license for Apple's code, so that's all moot.
Basically, it looks to me like the EFI bootloader's authors are of of luck in that their code must be distributed under APSL. So, if Pystar is fulfilling their requirements under the APSL (distribute source code) there is nothing anyone can do about it.
Except Apple that is. From what I've read, with this license, it looks like Apple has the sole right to terminate the license.
