I keep getting this email occadionally:

Your iCloud storage is almost full

Now for various reasons, I don’t want my children to be using iCloud to store data, files, photos or any of the sort. They’re free to use iMessages, and other Apple services like the App Store, etc, but not storage.

So I’ve set about blocking iCloud Storage API(s) via AdGuard Home tonight as well as ensuring that my local network (client users) cannot bypass DNS policies and get out other sneaky ways, because some applications will just use other DNS servers, or DOH or DOT.
