@digifox As a framework it doesn’t and can’t do anything to mitigate against sites deciding to trust only attesters that require immoral (anti-user freedom) criteria as part of their “baseline”.
The “holdback” mitigation is incapable of delivering the stated goals of making sure this isn’t usable for discrimination. The framework is prima facie immoral if the holdback percentage isn’t high enough to to make this useless for every case except measuring ad fraud. However, If holdback isn’t stable, even if the holdback percentage is high, sites can still discriminate against users that never pass it. If the set of held-back destinations is stable the set of held-back destinations becomes a useful and durable fingerprint. Furthermore there’s the relatively intractable problem of destinations colluding to share trust signals and enabling discrimination based on that.
There is no open web if an attestation framework gains critical mass, so such a framework must not be allowed to exist.
This is a credible proposal for DRM for websites in general. It would enable unbeatable adblock-blocking. It would prevent user customization for not just convenience but also accessibility.
I do not say this lightly: Enabling the forfeiture of control over the browsing experience is a fundamentally evil idea that must be rejected now, as it has been in the past, and we must remain vigilant against its reemergence in the future.
