Of course, you can frame the debate the other way around, i'm just making the point that "permissive/restrictive" means very little in this context and what matters really as a question is "do you wish huge corporations to benefit from your free-software work and expand on it to develop their own business, without EVER contributing anything back"? If yes, choose MIT and you'll probably regret it like so many open-source maintainers. Otherwise, choose (a)GPL and you probably won't regret it (at least i've never met someone so far who regretted choosing copyleft for their works, but it may exist of course).
