It's most likely Blue Diamond let them go. Though, not all of them. Some of them were already so used to living in the Zoo that Blue couldn't let them go. Instead, she just sent the more younger Zoomans go to live on Earth so they can become more accustomed to living like normal humans while the older ones stayed in the Zoo.
