It's easy enough to run unsigned apps, you just have to ctrl+click and select "open" then you'll get a different prompt that allows you to install the app anyway. I suppose you can argue that, if that's the case, what's the point? Well, if you think that a piece of software should be signed but it is in fact not signed properly, then that's a clue that it's been tampered with. If the software isn't signed at all, then at least I can decide whether I trust the source enough to install it.
