Performance. Most websites will work perfectly fine without JS, but there's always that one or two black sheep in there that run some JS loop that manages to redline a single core. When that happens it's always a bit of a hassle to find that one and disable it. It's comparatively less of a hassle to simply whitelist websites that i want to have JS. Plus, it's always amusing to find the few websites whose only purpose is to display some 500 words of simple text, and they fail to do even that when the JS is pulled out from under them.
