"Unless you take the time to uninstall the thing through ADB"
ADB is unfortunately not always capable of disabling unwanted junk on your phone.
I've got an el cheapo Alcatel Pixi with OEM bloatware installed which *can't* be removed via adb unless you root your phone. Default user via adb doesn't have sufficient permissions to remove the unpleasant apps, and "su" is unsurprisingly not present in the shell when you connect via adb.
Given that I use the device as an mp3 player, have never put a sim in it and won't be connecting it to wifi, the bloatware on my device doesn't really matter to me because it can't phone home, but I won't stand for that rubbish on a device I'm using as a smartphone.
