In all honesty I'm mostly interested in the classic green one, I have another green theme for the whole system that matches it however it's annoying because when my deck is offline I can't use the keyboard theme.
I might also want the night shift one as well, but mostly just the green one.
If one of the steps was leaking the source code then you could say that. Though who knows maybe AI reverse engineering will get good enough that we'll soon be able to turn the assembly code back into C++ or C. Then you can port the software to whatever you like.
With assembly you're very much limited to the hardware it targeted and without a huge amount of work the operating system that it targeted as well.
