This is a problem even without this. The account owner can get lists of all outbound calls of their victim’s line if they share a plan.
The fcc requires some remediation if a domestic abuse order is submitted but obviously that’s at the far end of the abuse cycle.
The issue here can be traced all the way to phone companies pushing the very concept of family plans because it makes churn more difficult.
An abuser can shut off their victim’s phone line on a whim with convenient online interfaces.
Phone companies don’t treat their customers will respect because their is no requirement. No one of adult age should be subjected to any of these controls simply because someone else pays.
The health industry has rules around this. The moment a child hits 18, their claims disappear and the parent loses access to medical records.
There is absolutely no reason phones should not have the same restrictions but the industry lacks the will and will until the fcc or other three letter agency forces the issue.
The prevalence of chromebooks in schools is another factor. While it has a keyboard and it’s common for them to use an external mouse, there is no file system that some website pretending to have a file system.
Both Chromebook’s and tablets break the fundamental rule of preparing children for the real work. There are few professions, if any that work solely off tablets and chromebooks.
