Web3 doesn’t care about privacy
In web3, your wallet ID (used for purchases and proposed for logins too) is an undeletable cookie that tracks you both online and off, and one that anyone can retrieve.This article seems to think that having a super cookie like this will make advertising less bad.  I think it will be the opposite - instead of only Google/Facebook doing it, you're now going to have every single shady operation under the sun now able to use/mine/combine your data however they please with zero controls (and unlike HTTP cookies they'll need exactly zero investment & zero infrastructure to do so, so there is no barrier to entry to start using this data)Web3 is the advertising world's ultimate dream situation.It allows significantly more invasive tracking by tying online and offline, cannot ever be deleted or changed, and the same cookie ID is shared across all aspects of your life (unless you use multiple wallets with one-per-site, but my understanding is that an anathema to web3 concepts about data ownership)
