Considering that just about all JS code running out there is likely non-free (except pure library demos usually), one could just run NoScript if they really wanted to block such code without losing out on much. It also seems like replacing non-free applications with free counterparts is quite a bit more complex in such an environment because it'd still have to interact with the (typically) non-free server infrastructure. Not to mention that doing so might actually be (sadly) illegal.
