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.
