It does mean exactly that. If parents want to control what their kids see online they can take control of the situation and limit screen time to where it can be supervised. It might even make sense to have legislation to ensure that that is possible (that schools can't require devices for young children, that device makers need to implement effective parental controls, etc.).

But that's not what the OSA is. Instead it's the government deciding how all kids should be parented. And of course it doesn't just affect the kids now because to be effective all adults need to prove they are not kids to view "harmful" materials, with all the chilling effects and collection of sensitive data that that entails.

Hence the original acknowledgement:
