Why would I bother when I can't do anything with it?
That's the point I'm making - not that I can't review the code, only that far fewer people will bother to do so since they can't use that code themselves.
That's totally subjective I think. In that case, the problem is in the people not wanting to do it, and not the license that hinders you. If you want to, you have what you need to fork the code and use it on your own software. But do it privately and for your own benefit without making anything public. Who is going to stop you?
