The child in that case is not the user (or at least not the owner). The user is the parent who configures the phone as they choose and loans it to the child. It's no different than Apple allowing a business to configure a MacBook as they choose, including tools to monitor its usage, and then offering that computer to one of their employees. The owner of the device gets to choose the privacy settings, not necessarily the end user.
I scanned through the comments here and I don’t think it’s been mentioned yet, but I would love, love, love to have an option added to settings to open links in a new tab (or possibly windows if some people would prefer that). The current behavior is to open in the current tab, which I am so unaccustomed to I keep closing the tab when I’m done with it rather than hitting the back arrow.
It’s quite jarring to not open in a new tab these days, especially for external links.
