This sums up my understanding of the current situation (https://www.gov.uk/government/publications/understand-the-im...)
That isn't anywhere near definitive.
Further it seems to me, this will just allow the tech companies to assume there are no kids, and remove the protections currently available.
Yes there is an issue of quantity, but it seems that we should be focussing on social norms for what is acceptable parenting in the 21st century. I'm 42, probably the lower age range for having a teenage kid, I have a couple of kids myself, and I'm not 100% sure on what the correct approach to take is, as I suspect the situation is for most other parents as the situation is so different to what we experienced at that age.
