I’m pessimistic about tech fixes, not because it can’t be done but because there is zero incentive. Like I said all the money and all the incentive is toward invading privacy.

Nobody is going to seriously try unless people are willing to pay for it in significant numbers. I don’t see that. Most people just don’t care or don’t understand.

There is also quite a bit of surface area to defend if you are trying to make privacy guarding OSes or browsers. Look at how hard it is to eliminate browser fingerprinting. There are so many ways to infer unique information.
