I feel like this is a bit too-optimistically describing an outcome which is unlikely, given how consumers have been slowly losing the same war for decades already.

The elephant in the room and the really "tricky part" involves powerful advertising and copyright-holding companies. They will (continue to) interpret that kind of user-agency as an existential threat. Their businesses revolve around deciding and knowing what you actually see and do with your computer, and their toolkit isn't just technical, but also economic and political.

That's why we already have problems with DRM, "felony contempt of business model" under the DMCA, browser fingerprinting, and everybody surrendering to arbitrary JS code controlling their computer. We capitulate not just to see an article or talk to a friend, but also to avoid our technical details getting into a secret un-appeal-able "suspicious" blacklist.
