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.
