they should abandon this concept altogether of pushing this burden onto the client-side (smartphone), they should be able to move any tracking logic server-side to get what they need from a mobile device, really I don't think companies should ever offload this burden onto a client-device, what are they tracking client-side (mousovers? keystrokes?) isn't this a bit invasive to the user?

They're tracking things like bounce rates and time on pages to find out who you interact with the most. Also, I'm sure they're analyzing how far you scroll the page, where you click away, and a variety of other things.
