How about consumers paying a little extra for their device? The way it's going, add sponsored big tech is dieing because click fraud detection is becoming too expensive. Either we give up privacy and track every user, or we let bots have at it, stop targeting ads to users and bill advertisers on bandwidth.
if you think consumers will pay more for the vague notion of privacy i have beachfront property in kansas to sell you. most normies either don't care ("I have nothing to hide ... do you?") or gave up already ("china / the government / big tech / all of the above already have all my data, why would I care if it's a bit more? what are they even going to do with it?" (sometimes, even "i like having relavent ads!")).
at my most pessimistic i can see a world where consumers pay MORE for attestation to continue to opt-in to society, or perhaps a ai-bot-free digital world.
