Intercepting non-obvious (in the sense that you can't just, like, open your wifi menu and see them) broadcasts is still hacking. Heck, even intercepting obvious (in the sense that it says "your data is not secure" on the screen of the people communicating) broadcasts is still hacking. Doing what Firesheep does, before Firesheep, was hacking. And then someone made Firesheep and it was still hacking, but now anyone could do it by clicking a few buttons, without any hacking skill whatsoever, not even using a command line, so it was finally patched.
