Carrier bloatware apps are quite an issue in the US, where many smartphones ship with almost as much useless junk as they do genuinely necessary applications. This junk is lovingly called "crapware," "bloatware," or "shit" interchangeably by those in the smartphone community. Because it is. This disdain largely stems from the fact that many bloatware apps can't be fully uninstalled, only disabled (some can't even manage to do that).
In Android 5.0, Google is hoping to give everyone another option: don't be so awful about it.
