I don't accept the argument: "Software is software". Why is GPL better than all other licenses, for all software?
You seem to be distinguishing between two things, but I cannot see what they are.
Three orders of magnitude of what? What is being measured? Do you mean that platforms are bigger than modules?
What I meant is that the software is used differently, and it is developed differently. It seems obvious to me that the ideal licensing for software that is vastly different from these examples of gargantuan/universal FOSS might not be GPL.
