Why do we seem to better tolerate preinstalled or system-update app installs vs pushed installs? I guess you might at least know what's getting installed by system updates ahead of time, but most don't pay attention to that and are only surprised once they see the new app icon. I know we haven't really owned our own phones in some time, but this does feel like a turning point.
