> the UUIDs could also be service specific, so they cannot be cross referenced across different sites in case of leaks.
Assuming services play nice. What if they start sharing UUIDs amongst each other, for example for advertising purposes?
Worse what is stopping companies from creating both service and verifier? Nothing, as Amazon already has both. I do not trust them not to abuse this.
And even if in theory all companies do the respect my privacy. I am one government away, from seeing a law passed, that makes it mandatory to report all UUIDs to the government. The potential for tracking is off the charts.
Right now it takes forever to trace everything. You can realistically only do it for a select targets. If you implement this UUID system, suddenly it becomes much easier to trace everyone's actions.
