Well yeah, but that's everywhere. More realistically I think it's because browsers are the biggest software delivery platform every created (and likely that ever will be created until we get some sort of neural/in-body interface), and they change faster than regular desktop software ever could. The browser is so popular as a software distribution method, it now competes with GTK/QT/Cocoa/etc for (large amounts of) "RAMshare" on your neighborhood desktop.
