If that's the case then it still has nothing to do with the feds tracing Monero, but instead is about using KYC exchanges i.e bad OPSEC.
Even the most anonymous cryptocurrency will not protect you if you KYC yourself.

> it still has nothing to do with the feds tracing Monero
It has everything to do with the feds tracing monero. You know why they knew he used that exchange? Because they traced his monero to it. If you stop them from tracing the money in the first place, they never learn what exchange he uses, and thus they don't know who to subpoena for user info.
They don't claim at all that they traced Monero. In fact they specifically mention tracing Bitcoin and DO NOT mention Monero at the top of the section just before they
"As described below,
Crypto Account-1 appears to have received substantial funds from Marketplace-1. Using software
tools, law enforcement officers have reviewed the publicly available Bitcoin digital ledger, as well
as the transaction history of Crypto Account-1, and learned the following, in substance and in part:"
They don't claim to have any transparency into his XMR transactions. According to them, they we watching the BTC blockchain, the swap service and the CEX.
LE got this information by identifying the person and their BTC addresses FIRST
And then watched them send their BTC through the swap and saw the Monero appear in their CEX account.
Zero transparency into the Monero transactions.
You are a liar calling this "tracing Monero"
And that's just the FIRST of your "sources"
this is exactly right. they were already watching his account in the CEX and saw the monero arrive there.
the moral is
"don't think that sending your surveiled Bitcoin through a swap to your exchange account makes them clean"
