The question we should be asking is how much that we value for other good reasons we are willing to give up in exchange for the possibility of improving the protection of our children, when there is no crystal ball that tells us either how much of an improvement any given measure would actually make or how much of the potential harm from giving something else up would actually be realised.
Until we view these kinds of rights and protections issues as a balancing act with legitimate arguments on both sides but also genuine concerns from both sides it's impossible to even have an intelligent debate on the ethics, never mind write good laws with all the extra practical concerns that legislation and enforcement introduce.
1. I don't believe children will really be "saved" from viewing/reading harmful content - if they really want to see something, they will simply find a way around it, but also remember this is a *UK-only* thing!
2. I don't believe for a second that the security apparatus won't have unchecked access to the dataGiven who the government here currently are it's hardly surprising that they resort to attention-grabbing soundbites. With a bit of luck the Tories will boot Boris before too long and that'll take many of his current Cabinet out of the picture as well since they were seemingly chosen more for their expected loyalty to Boris than any particular expertise or competence. Then at the very least there is a mini-reset in government and some of the more headline-grabbing but questionable policies of the Johnson administration might be quietly sidelined while whoever takes over desperately tries to steady the ship before the next general election. Although of course they quietly passed legislation earlier this year that pushed the latest possible date for that election all the way back to January 2025...
So instead of parents actually installing and/or configuring and/or actually using all of the different parental controls that are already available to stop their kids seeing stuff they shouldn't, they want all the rest of us to deal with the bullshit, while not solving the problem.
It establishes the age and id of UK children to websites and services. However, unless all these services children use are siloed off from the rest of the internet and UK only, bad people from other countries (and those in the UK savvy enough to mask themselves behind some kind of VPN/TOR) will still be able to use these services without having their ids established the same way, and will keep trying and sometimes succeed to groom and abuse children.
