There are a lot of GOP-controller legislatures in the USA pushing through so-called “child protection” laws, but there’s a toll in the form of impacting people’s rights and data privacy. Most of these bills involve requiring adults to upload a copy of their photo ID.
What good is it for the system to know, if the system disregards that information right after auth? Effectively it’s like no one ever knew.
You’re confusing intents and capabilities. When we’re talking about security and privacy we have to talk about capabilities. Not intents.
Somebody could have the best intentions, but you don’t want to give them the capability to hurt you. If it’s not necessary. So does a daycare need a volunteer militia to hang out all day cleaning their weapons? Probably not, the capability even if well intended is antithetical to the security and welfare of the children.
Even if the intention is good today, putting the framework and capability in just invites future corruption.
Hence why such a system would need to be open source and publicly audited.
