@xj9 maybe - but companies should at least be held to account under existing law (I live in the EU so ePrivacy and GDPR). There is a wider problem of tracking in apps, OSes, IOT devices and pervasive tracking of WiFi, Bluetooth and facial recognition such browsers can't solve. Also, deceptive banners about cookies are commonplace, so risks apply to whitelisting too. Imagine you are told you are consenting to sex with someone, but they swap in someone else.
