And I can install a 'Skype stub' application that doesn't do a thing unless you start it as well.

It's still crapware, unwanted and useless. If I want anything but the Play Store (honestly.. I shudder, whenever I have to write/say that name. How can you take that name serious, ever?) itself, I can install it. Preinstalling applications is a Bad Idea™ most of the time, clutter if you're feeling nice, abusing the market position otherwise.

Why would I need Chrome on my mobile? Why is it impossible to remove it?
