And the root user is the owner of the computer. This is saying that if you buy an Android device you are not granted the privilege of owning the device.
The mindset of mobile developers is to treat the end user as an adversary. You're not meant to control your device beyond what the gatekeepers of the walled garden want you to do. They want to operate by the television model where there are a privileged few producers delivering content to the masses. It's the antithesis to the internet model of an information economy where anyone can communicate with anyone else and not need a middle-man regulating their conversation.
Most manufactorers supply tools to root your device. It's about the same as ubuntu having a root user without a password you still have to set.
Only if you buy your device from a carrier that locks it, you will have trouble with getting root access. But you should be angry at them, not at Google. Google is making Android safer to use for the general public. This ease of use and hanhdolding is one of the reasons Android is actually popular with non tech-savy people instead of any Linux desktop distro.
