rooted/unlocked your phone. opening up root access to your phone means you can essentially access any file on your phone, including system files. so, if you have "root" access you could essentially go into the system/app folder and take out goggles yourself.
I personally don't think its malicious, but it is VERY aggravating when you can't uninstall an app without root access (visual voice mail anyone?). But you did make a valid point in that it is foolish to trust something because of a brand name.
or remove it with a custom script within terminal emulator, but thats a long explanation in itself
