I'm not the original poster, but I tink they may have meant to draw a connection between credit bureaus collecting sensitive personal financial and identity information that can reveal potential targets to criminals and KYC, which has the same danger.

Both collect sensitive financial information and when leaked or leveraged by bad actors could be used to targert well heeled people or low hanging fruit, both in crypto and tradfi.

One of Monero's great strengths is that it helps with this. But a lot of that perceived protection through obfuscation of wallet value is harmed when it is acquired using KYC because that can reveal things like who has how much.

Unlike BTC or other public ledgers, the threat actor would have to hope you still had that much in your possession since they couldn't verify the balance on the blockchain in real time. But if someone had huge amounts of value shown acquired through KYC, even if moved into private XMR wallets, it would be a relatively safe bet that they still controlled enough liquid value in currency or other goods to target.
