In this explanation, clearly the exchanges themselves have done KYC and have your entire history on-chain. They can sell this to any marketing agency…
For example, Coinbase:

- lrvick 5y agoI would never expect privacy from exchanges. Some of my clients directly pay me in Bitcoin for services I render for them. Funds go directly from wallets my clients control to wallets I control as if they handed me cash. No exchanges involved. We report taxable events but the transaction histories need not be shared with central third party private companies. Also even when you buy Bitcoin on exchanges you can always trade it for Monero via a number of swap services then back to Bitcoin again. Now you broke the history and have private Bitcoin again.
