Thank you for the links to Wikipedia and identity.com on that other thread. I've yet to wrap my head around how zero-knowledge proof could work for such a basic assertion as "user is of legal age", which calls for a 0 or 1 answer. It seems very different from the examples given of polynomial computations to prove knowledge of an exponent in a complex math expression. I can't see what could prevent any client to simply lie about the answer here.
Could you recommend a specific video of his where everything is laid out?
Some people seem to think that blending in is the best/only strategy to avoid being tracked and profiled. The developer of GrapheneOS advocates for this in no uncertain terms, encouraging users of his Vanadium web browser not to use uBlock or NoScript, yet also claims that DNS-level blocking is the only way to block content without sticking out like a sore thumb. I personally question his assumptions regarding this. All it would take for a big ad broker like Google, Amazon, Baidu to detect this would be for them to analyze their web server logfiles to spot which distinct clients (IP addr. x date x time x User-Agent string x other fingerprints) connect to their front-ends but don't connect to the analytics or ad-network servers during the same page-loading time frame.
One might also wonder whether ad brokers put deals in place with their customers to get read access to these customer's web server logfiles to do the same kind of analysis in exchange for cheaper rates. Or perhaps under the guise of "let us offload you of these complicated analytics tasks, just show us your logfiles and we'll take it from there."
