Some fair points to consider.

Consistency at school means more and more parents and families are practicing their internet exposure the same way as well.

How this is being done might not be the greatest, and it might change how social media is used, or invite the next thing after social media. Most platforms have dreamt of being a users core identity service as well and that might be it.

The multiple independent studies that show the effect on children developing brains from scrolling and screens alone, let alone the content (be it social media etc) is something worth offering an approach to as well, parents can't be expected to be DIY and self-educate against the types of software that are so optimized to achieve their independent objective of the software - keep us using them.
